Abstract: Multi-semiconductor SSPCs that solve bus level problems affecting systems as well as controller level problems affecting individual multi-semiconductor SSPCs are disclosed. Bus level and controller level problems adversely affect multi-semiconductor SSPCs and their associated systems. The disclosed multi-semiconductor SSPCs solve both bus level and controller level problems by implementing controlled rate-change of voltage (dv/dt) ramp-on rate, to ensure that the voltage on the input bus does not collapse when a multi-semiconductor SSPC is commanded closed and that a minimum amount of power is being dissipated evenly across the switching semiconductors.

Abstract: The runtime retargeting approaches discussed herein can enable real time adaptation of character and object motion. In particular, fixed-source motion can be dynamically adjusted to variable situations encountered during runtime. In this way, the runtime retargeting approaches discussed herein can preserve the intent, visual quality, and essence of such fixed-source motion, while modifying it to meet new physical constraints or goals.

Abstract: An image forming apparatus includes: a controller that allows a display device to display a settings screen for setting of a function by a user and executes a job based on a user setting made through the settings screen; and a backup device that backs up as backup data the user setting on a storage device each time the user setting is made.

Abstract: An apparatus and method to detect and locate electrical faults in an insulated supply conductor sheathed in a conductive screen is disclosed. The apparatus is positioned along the supply conductor between a power supply and an electrical load. The conductive screen is coupled to an electrical ground via a first resistive element. A voltage on the conductive screen is sensed and compared to a threshold to determine whether a fault condition exists. The apparatus is configured to inject a voltage pulse to the conductive screen and detect a reflected pulse therefrom. The location of the fault condition is determined based on an elapsed time between the injection of the voltage pulse and the detection of the reflected pulse.

Abstract: A system enables an arbitrary number of items to be indexed in a geographic region that provides a predictable query response time across a sharded database. Items indexed to the geographic region are stored on a single shard and additional items are added to that shard as long as an overflow condition indicative of undesirable query response times is not met. If the overflow condition is met the system expands the storage of items indexed to the geographic region to one or more additional shards in order to maintain predictable query response times. The system may maintain a shard count representing the total number of shards being used to store items corresponding to a geographic region, which can be used to query one or more relevant shards. The system may apply deterministic hashing in order to evenly distribute shards across database nodes of the sharded database.

Abstract: An apparatus includes a fiber-optic connector configured to be connected between one or more optical fibers having fiber cores and a photonic integrated circuit (PIC) including vertical-coupling elements. The fiber-optic connector includes a polarization beam splitter and a patterned birefringent plate. The polarization beam splitter splits an incident light beam from a fiber core into first and second beams having first and second polarizations, respectively. The patterned birefringent plate includes a first region (having a first optical birefringence) and a second region (having a second optical birefringence). The difference in the first and second optical birefringence is caused by (i) applying localized heating to the first region without applying localized heating to the second region to cause the first region to have a lower birefringence as compared to the second region, or (ii) applying different amounts of localized heating to the first and second regions to produce different birefringence.
