Abstract: Systems, devices, and methods for cleaning a sensor are provided. A sensor can include a housing. The housing can include a curved lens. The sensor can further include an inlet configured to receive a pressurized fluid. The sensor can further include a rotatable fluid distributor positioned within the housing. The rotatable fluid distributor can be configured to receive the pressurized fluid from the inlet. The sensor can further include a plurality of nozzles positioned around an exterior of the housing. Each of the plurality of nozzles can be configured to direct a flow of the pressurized fluid onto at least a portion of the curved lens. When the pressurized fluid is provided to the inlet, the rotatable fluid distributor can be configured to receive the pressurized fluid from the inlet and distribute the pressurized fluid to only a subset of the plurality of nozzles at any time.

Abstract: Systems, methods, tangible non-transitory computer-readable media, and devices associated with detecting and locating sounds are provided. For example, sound data associated with sounds can be received. The sounds can include source sounds and background sounds received by microphones. Based on the sound data, time differences can be determined. Each of the time differences can include a time difference between receipt of a source sound and receipt of a background sound at each of the microphones respectively. A set of the source sounds can be synchronized based on the time differences. An amplified source sound can be generated based on a combination of the synchronized set of the source sounds. A source location of the source sounds can be determined based on the amplified source sound. Based on the source location, control signals can be generated in order to change actions performed by an autonomous vehicle.

Abstract: Systems, devices, and methods for cleaning a sensor are provided. A sensor can include a housing, a rotatable disc, a plurality of nozzles, an inlet configured to receive a pressurized fluid, and one or more distribution channels configured to direct the pressurized fluid from the inlet to the rotatable disc. The housing can include a curved lens and a channel circumferentially positioned around a base of the housing. The rotatable disc can be positioned within the channel and configured to rotate around at least a portion of the housing within the channel. The plurality of nozzles can be positioned on the rotatable disc. The rotatable disc can direct the pressurized fluid onto at least a portion of the curved lens via the plurality of nozzles, thereby causing the rotatable disc to rotate around at least the portion of the housing.

Abstract: A service platform provides automated speech based services over a telephone network. It includes a speech processor with associated memory, to provide services such as speech recognition, speaker recognition, speaker verification and speech synthesis. A line interface terminates a number of telephony channels of the network while a speech bus carries speech signals between the line interface and the speech processor. A control processor controls routing of speech signals over the speech bus and a control bus connects the control processor with the speech processor and the line interface. A separate memory holds speech processing software and a data link connects the memory with the speech processor to load programs into the speech processor during run time in the event that appropriate software does not exist on the speech processor in a free state.
