The Peripheral 1x2 WORK



PCI Express Mini Card, commonly abbreviated as mPCIe, or Mini PCIe, is a newer form-factor for PCI Express devices. Designed with the older Mini PCI standard in mind they are the same basic form-factor (commonly used in small-form-factor devices like laptops and other portables) but lack the retention clips of Mini PCI. Unlike the original PCI Express bus, Mini PCIe provides both the standard PCI Express and USB 2.0 signals, allowing flexibility in peripheral design. The standard is highly suitable for industrial automation and test in vehicle, mobile, or any other shock / vibration sensitive application.

The Manhattan Hi-Speed USB 2.0 Automatic Sharing Switch easily allows two computers to share a USB device. It's ideal for home and office use where users need to share a USB cable modem, printer, digital camera, scanner, external storage drive or other peripheral. Use the convenient access-on-demand switching for activation with a single click of an onscreen button, or use on-board switches to manually select an active computer.


While USB 4 may be the latest and fastest generation, the most common USB ports on PCs and peripherals have a "3" in the version number, specifically USB 3.2 or USB 3.1 or even 3.0. When you're looking at spec sheets, you'll also also see generation numbers after the USB 3.2 or 3.1 so, for example, there's USB 3.2 Gen 1, USB 3.2 Gen 2 and even USB 3.2 Gen 2x2. And yet some ports with different version numbers actually have the same speed! Confused yet?


The different USB 3.x version numbers exist purely because the number has been iterated with each speed advancement. In 2008, the USB 3.0 standard launched, bringing USB up to 5 Gbps, a huge leap from the 480 Mbps speed of USB 2.0, and for many years that was as fast as USB could go. In fact, even today, the vast majority of USB ports and products don't go beyond 5 Gbps nor do you need them to. Many peripherals don't even need to go beyond USB 2.0.


If you have a USB 3.2 Gen 2 port and want to take advantage of its 10 Gbps speed, look for a cable that supports 10 Gbps (it could be USB 3.2 Gen 2 or USB 3.1 Gen 2) and a peripheral that does the same. If you want to get 20 Gbps speeds, all three pieces: the port, the peripheral and the cable, must support that speed.


USB 3.2 Gen 1 and USB 3.1 Gen 1 run at up to 5 Gbps speeds, which in and of itself, is more than most peripherals require on their own. Wired mice and keyboards, even those with high polling rates, don't even max out the USB 2.0's 480 Mbps limit. However, some of the best webcams, require USB 3.2 / 3.1 / 3.0 connectivity, especially when they're delivering 30 fps at 2K or 4K resolutions.


If you're using a USB hub, you'll want at least a 5 Gbps connection, because all of the peripherals connected to that hub will be sharing that bandwidth. So, if you have a mouse, a keyboard and a webcam all plugged into the same hub, they will definitely need at least the 5 Gbps that USB 3.2 Gen 1 / USB 3.1 Gen 1 provides.


The macula is the central area of the retina responsible for central vision. It makes up only a small part of the retina, yet it is much more sensitive to detail than the rest of the retina (called the peripheral retina). The macula allows you to do things like thread a needle, read small print, and read street signs, whilst the peripheral retina gives you side vision.


Age-Related Macular Degeneration or AMD is a retinal eye disease that causes progressive loss of central vision whilst leaving the peripheral vision intact. This progressive degeneration affects the macula, hence it makes it difficult to do things like read, drive, write, recognise faces and perform daily tasks.


With macular degeneration, you may have symptoms such as blurriness or dark areas or distortion in your central vision, and perhaps permanent loss of your central vision. It usually does not affect peripheral vision. A change in colour vision may also occur as the macula is the part of the retina responsible for colour vision. Many people are not aware that they have the disease until they have a noticeable vision problem or until it is discovered during an eye examination.


The Tampa Trephine (Martin Marietta Speciality Components, Largo, FL, U.S.A.) penetrating keratoplasty technique uses a 7.0-mm corneal donor button with six rectangular 1 x 2-mm tabs of Bowman's layer, 75 microns in thickness, which are inserted into the recipient stroma beneath Bowman's layer. We evaluated the safety of the Tampa Trephine tissue-trephination method on the cat corneal endothelium combining vital staining and scanning electron microscopy, comparing it with the standard Weck trephination technique. The Tampa Trephine tissue trephination produces a donor button with a 6.7-mm diameter central area of normal endothelium. Localized peripheral areas of cellular loss, endothelial and Descemet's tears, endothelial detachment, and folding along the border of the trephination were observed with the Tampa Trephine method, all located in an area of


In general, two functional modes of vision, focal and ambient, are distinguishable, with different functional characteristics and underlying information processing. Focal vision is assumed to be responsible for detecting the physical characteristics of environmental objects (that are usually fixated in the central visual field), while ambient vision is concerned with the detection of spatial characteristics of the surrounding (i.e., peripheral) visual world [6]. Studies on visual functions have used various definitions for the central and peripheral visual fields. One neuro-anatomical definition equates central vision with the central 2 to 4 of the visual field, based on the retinal distribution of photoreceptors [21]. Another definition indicates that central vision covers the central 7 of the visual field because visual inputs from the 7 visual field project onto the area of the primary visual cortex that processes central vision [22]. Based on these definitions, Berencsi, Ishihara, and Imanaka [23] used both 4 and 7 visual angles for manipulating the central and peripheral vision conditions. In contrast, Nougier, Bard, Fleury & Teasdale [24, 25], Paulus et al. [18], Brandt et al. [2] and Previc & Neel [26], manipulated the central vision using visual fields of 10, 30, and up to 60, respectively.


In contrast, Berencsi et al. [23] used occlusion manipulation to differentiate the central and peripheral visual fields, presenting stationary random-dot stimuli exclusively in either the central or peripheral visual field. Berencsi et al. measured the trajectory of the center of pressure (CoP) during quiet standing. The CoP area (a primary indicator of the extent of postural sway) was significantly smaller for peripheral vision than that for central vision. This indicated that the visual stimuli in the peripheral rather than central visual field contributed more effectively to enable stable standing. Unfortunately, Berencsi et al. manipulated the visual field alone and did not manipulate the optical flow induced by postural sway. It was therefore far from clear whether the contribution that stabilized posture came from peripheral visual inputs per se or the optical flow likely to occur in the peripheral visual field.


Envelopment area for the four visual conditions (full vision [FV], central vision [CV], peripheral vision [PV], and no dot [ND] condition) for both the desktop display (DTD) and head-mounted display (HMD) conditions. The x-axis denotes the visual condition, with the y-axis denoting the size of the envelopment area. Error bars indicate the standard deviation (SD).

Both the PV and FV conditions for the DTD involved the presentation of visual stimuli in the peripheral visual field with an optical flow due to postural sway occurring in quiet standing. In contrast, no postural advantage appeared at the PV and FV conditions for the HMD, suggesting that visual inputs in the peripheral visual field per se do not affect stable quiet standing unless optical flow is present. As the features of postural sway did not significantly differ between the CV and ND conditions for the DTD, the visual stimuli presented in the central visual field might not contribute to stable quiet standing, even if optical flow is present. These results therefore clearly suggest that the optical flow in the peripheral visual field contributes to better/stable postural control in quiet standing. 041b061a72
