Abstract: Implementations relate to a spherical wheel drive and mounting. In some implementations, a wheel mechanism includes a spherical wheel, a base, and a rotary bearing coupled to the base and contacting a surface of the spherical wheel, where the rotary bearing configured to allow the spherical wheel to rotate. The wheel mechanism includes an omni wheel coupled to the base and engaged with a surface of the spherical wheel, and an actuator coupled to the base and to the omni wheel, where the actuator configured to rotate the omni wheel to cause rotation of the spherical wheel.

Abstract: Implementations relate to a brake mechanism for a spherical wheel. In some implementations, a wheel mechanism includes a spherical wheel and a base coupled to the spherical wheel via a rotary bearing contacting a surface of the spherical wheel, where the rotary bearing is configured to allow the spherical wheel to rotate. The wheel mechanism includes a brake ring coupled to the base and configured to selectively engage and disengage the surface of the spherical wheel, where the brake ring provides friction opposing rotation of the spherical wheel when engaged.

Abstract: An imaging system for deployment within a high-radiation environment. The imaging system has an imaging array of photosensitive pixels, each of which contains a sense gate for integrating photogenerated charge during the course of a frame and an amplifier transistor for sampling voltage on the sense gate. Each pixel also contains an inject gate and select and reset FETs, for operation as a charge injection device (CID). Moreover, a circuit including a monitor transistor on each polysilicon layer of the imaging array provides a threshold voltage monitor signal used to compensate a drive signal applied to the array on the basis of threshold voltage shifts induced by exposure to radiation. The array is contained within a remote head that may be evacuated and temperature-controlled and that may contain radiation-hardened drive electronics for generating drive signals upon receipt of a start pulse received from a camera control unit located at a significant distance from the remote head.

Abstract: A protected arc tube mounting assembly for a metal halide arc lamp includes: a fused quartz arc tube (41) having a discharge space (42) with a discharge-sustaining fill and discharge electrodes (43, 44) at opposite ends of the discharge space (42); a fused quartz protective shroud (49); and a starter electrode (61) adjacent to one of the discharge electrodes (44) connected to a starter circuit (63). The arc tube (41) is suspended from above by a lead-through (47) connected to a first support member (56), and is supported from below by another lead-through (48) connected to a second support member (57). Further support is provided to the arc tube (41) by the first support member (56) via the starter circuit (63). The shroud (49) is supported by a pair of mounting clips (67, 68) attached to the first support member (56).

Abstract: An arc tube mounting assembly (1) for a metal halide arc lamp (10) includes frame members (8, 9) for supporting an arc tube (2). The arc tube (2) is supported from above by a looped frame member (8) having a loop (8A) which extends along opposing sides, and across top and base ends (2A, 2B) of the arc tube (2), thus evenly distributing the current to discharge electrode 7, thereby cancelling magnetic forces which could displace the arc from the center of the arc tube (2), resulting in improved lumen maintenance and extended life. A centering circle (8B) of the frame member (8) wraps around the lower ceramic end plug (4), providing coaxial alignment of the arc tube (2) and the tubular outer envelope (11).

Abstract: Random access charge transfer devices are provided in which it is possible to simultaneously read electric charge that is stored within each detection element (pixel) that is in one of any desired combination of columns and that is also in one of any desired combination of rows. It is also possible to simultaneously read electric charge stored within each detection element or pixel in at least one selected column or row. In addition, it is possible to simultaneously cause injection of some or all of the electric charge stored in each detection element in one of any desired combination of columns and also in one of any desired combination of rows, or to simultaneously cause injection of some or all of the electric charge stored in each detection element in at least one selected column or row.

Abstract: A computer system employs a repeater unit which repowers a serial channel link. The repeater unit also monitors and records non-idle usage and errors for both directions of the repeated serial link. Non-idle usage of the serial link is recorded as a number of seconds that non-idle traffic flowed in the link over a given period of time. Link serial code violations and loss-of-light transitions are also counted. Link code violations are counted with an accuracy that permits targeted serial link bit-error rates, of no more than one bit error in approximately two months, to be accurately verified for the first time in a normal customer environment. The repeater unit permits an attached monitoring computer to read and reset all its usage and error counters as often as required by the customer, and without losing any counts of any counted event.
