Abstract: A method for configuring a system having a wearable optical unit is disclosed. The method includes powering on the system, and in response to the system being powered on, using one or more processors to control the system to: determine whether to cause the system to run a configuration workflow, and in response to determining to cause the system to run the configuration workflow, (a) control the system in connection with configuring an interpupillary distance (IPD) for a user of the system, (b) determine whether the IPD is configured for the user, and (c) in response to determining that the IPD is configured for the user, control the system in connection with configuring a focus of the optical unit.

Abstract: Systems and methods are provided for detecting and preventing sleep onset in a user. The method can include, for example, monitoring the user's heart rate, establishing a baseline average heart rate over a period of time, establishing a threshold heart rate that is less than the baseline average heart rate, detecting a drop in the user's heart rate below the threshold, and in response to detecting the drop, initiating a sleep prevention program.

Abstract: A storage container for a refrigerator appliance is provided. A supplemental storage shelf is mounted to the storage container. The supplemental storage shelf is configured for selective positioning along a vertical direction relative to the storage container. In such a manner, the supplemental storage shelf can be easily or conveniently stored when not in use.

Abstract: Crude chlorosilane streams containing lower-boiling chlorosilanes and higher-boiling chlorosilanes are separated by contacting them with a distillation aid. The lower-boiling chlorosilanes are separated from the crude chlorosilane stream, and then the distillation aid and the higher-boiling chlorosilanes are separated from one another. The distillation aid is a mono-cyano-substituted organic compound, a nitro-substituted organic compound, a mono-cyano-substituted organosilicon compound, a nitro-substituted organosilicon compound, or a mixture thereof. These distillation aids increase the relative volatility of crude chlorosilane streams such as methyltrichlorosilane and dimethyldichlorosilane resulting in improved separation at lower capital and/or fixed costs.

Abstract: The invention pertains to a method of passivating direct process solids (1) and to passivated and quenched compositions resulting from said method. The method of passivating direct process solids (1) according to the invention comprises combining direct process solids (1) with a passivating composition comprising clay (2), base (3), and water (4). The passivated composition of the invention comprises direct process solids (1) and a passivating composition comprising clay (2), base (3), and water (4). The quenched composition of the invention comprises the passivated composition, wherein the passivated composition has been held for a sufficient period of time for the reactive species from the direct process solids to be substantially quenched and/or oxidized.

Abstract: A process for producing cyclic polysiloxanes is disclosed. The first step of the process comprises combining a poiysiloxane, a cafaiyst and a high boiling endblocker, wherein the catalyst is selected from the group consisting of a phosphazene base and a carborane acid.

Abstract: An internet user visits a web site and requests to see imagery from a specified one of a plurality of video cameras. At a system associated with the web site, a load distribution server assigns the user's request to one of a plurality of image servers. The assigned image server first checks its local image cache to see whether a recent image from the specified camera is stored there. If so, the image from that local image cache is sent to the user. If the local image cache does not have a recent image from the requested camera, the assigned image server then checks its local request cache to see whether an earlier process has recently requested the same imagery. If so, then the assigned image server simply waits for the earlier process to compete instead of initiating its own new image retrieval request. If no earlier process has recently requested the same imagery, the assigned image server issues its own image retrieval request.

Abstract: A compressor for compressing a gas comprises an impeller wheel mounted within a housing (2) defining an inlet (8) and an outlet (6). The inlet (8) has a plurality of apertures (20) in the form of bores or grooves defined in its surface that serve as an integral silencer. The inlet (8) may comprise a map-width enhanced structure (4) with the bores provided on one to a number of surfaces. The design provides for a compact and efficient compressor with noise reduction such that higher pressure ratio designs may be adopted. The apertures (20) may be provided in the housing (2) that defines the inlet (8) or in a separate insert.

Abstract: A shield may be provided over a printer developer roll, adjacent to a doctor blade, to reduce toner dusting and toner accumulations. The shield may slightly conform to the curvature of the developer roll in some embodiments. As a result, toner accumulations on surfaces which the customer must touch may be reduced.

Abstract: In a two piece toner cartridge assembly, as typically used in a computer and/or facsimile printing device, comprising separable photoconductor and developer units a unique coupling device is provided whereby the cartridge assembly may be removed from the printing device without the photoconductor unit separating from the developer unit for paper jam clearance or unit replacement. However, if desired the developer unit may be separately removed from the printing device for servicing or replacement without removal of the photoconductor unit.

Bracket may include a pair of guides that extend outward to receive the ends of the charge roller. A biasing device may be positioned to bias the charge roller against the photoconductive drum. The guides may include an opening sized to allow the charge roller to move and maintain contact with the photoconductive drum. A mounting surface may be positioned on the bracket for receiving adhesive to mount the blade. In one embodiment, the bracket is constructed of an electrically conductive material such that a charge introduced to the bracket is delivered to the charge roller.
