Abstract: In one embodiment, a method includes receiving sensor data associated with an object external to a vehicle. The sensor data includes a sequence of data packets. Each data packet corresponds to a time frame in a sequence of time frames. The method includes determining a classification of the object based at least on the sensor data, determining that a particular data packet corresponding to a particular time frame in the sequence of time frames is corrupt or missing, generating a replacement data packet based on one or more data packets that correspond to one or more time frames adjacent to the particular time frame, generating a sequence of visual representations of the object corresponding to the sequence of time frames. At least one visual representation in the sequence of visual representations corresponding to the particular time frame is generated based on the replacement data packet.

Abstract: In one embodiment, a method includes determining a plurality of available locations for a vehicle to pick up or drop off a user in an area based on sensor data that is captured by the vehicle and is associated with physical characteristics of the area. The method includes calculating a viability value for each of the plurality of available locations. The viability value is calculated based on the physical characteristics of the area as determined from the sensor data. The method includes ranking the plurality of available locations according to the viability values of the plurality of available locations. An available location with a higher viability value is ranked above an available location with a lower viability value. The method includes sending instructions to present, on a computing device, one or more selectable locations of the plurality of available locations based on the ranking.

Abstract: A method and system are disclosed for blind decoding of Bluetooth packets. According to one aspect, a method of decoding packets includes detecting a packet using blind LAP detection. The method also includes estimating a duration of a payload of the packet and decoding a payload of the packet over the estimated duration according to each of a plurality of forward error correction (FEC) coding rates to produce a packet header. For each of a plurality of de-whitening seeds, the method includes performing de-whitening, extraction and reverse decoding on the packet header to produce a plurality of candidate upper address parts (UAPs). The method includes obtaining a subset of the candidate UAPs, each candidate UAP having a corresponding CRC code, and forming an ordered list of candidate packet types based at least in part on the estimated duration. The method includes performing a CRC to select a UAP.

Abstract: A computer system for monitoring and controlling remote services comprises at least one first processor executing a first set of instructions and at least one second processor executing a second set of instructions. The first processor and the second processor communicate through a packet-switched network. The second set of instructions causes the second processor to initiate a data communication with the first processor by means of a remote procedure call to the first processor, identify itself to the first processor, and accept commands from the first processor. The first set of instructions causes the first processor, after communications are initiated by the second processor, to receive data from the second processor and send control instructions to the second processor. The first processor is typically a host server computer and the second processor is typically a remote terminal unit.
