Abstract: Various embodiments of the present application set forth a computer-implemented method comprising aggregating positional signals that were received from device sensors, where each positional signal has an observed signal strength, identifying a subset of the positional signals, where each positional signal in the subset was received by a device sensor while the device sensor was located within the physical location, for each positional signal, generating, by an estimation device and based at least on a position of the device sensor, an approximate object height for an object located at the physical location, for each approximate object height, determining an expected signal strength for the positional signal corresponding to the approximate object height, generating a cost value that is based on a difference between the expected signal strength and the observed signal strength, and determining, by the estimation device and based on the cost values, an estimated object height.

Abstract: A device for collecting vehicle on-board diagnostics (OBO) data is disclosed, together with an associated method of collecting OBD data in such devices. In embodiments, the OBO data collection device includes a connector for connecting the device to a vehicle OBO port to receive OBO data and power and a processor for controlling collection of the OBO data. The processor is arranged to determine a vehicle engine state by monitoring a voltage at the connector, taken in combination with OBO data relating to vehicle speed and/or engine revolutions. Such devices are able to reliably detect both engine ‘on’ and ‘off’ states in modern vehicles that use “smart charging” technology.

Abstract: A device for collecting vehicle on-board diagnostics (OBD) data is disclosed, together with an associated method of collecting OBD data in such devices. In embodiments, the OBD data collection device includes a connector 8 for connecting the device to a vehicle OBD port to receive OBD data and power and a processor 10 for controlling collection of the OBD data. The processor 10 is arranged to determine a vehicle engine state by monitoring a voltage at the connector 8, taken in combination with OBD data relating to vehicle speed and/or engine revolutions. Such devices are able to reliably detect both engine ‘on’ and ‘off’ states in modern vehicles that use “smart charging” technology.

Abstract: A prosthesis joint including a base, a coupling element for attachment to a body part or a prosthesis section, which is attached to the base, and an attachment device for attachment to a prosthesis device, which is coupled to the base and pivotable around at least one axis. A locking device is coupled to the coupling element and operates to selectively block and enable movement of the attachment device with respect to the base providing locked and unlocked positions, respectively. A retention element is carried by at least one of the base and coupling elements and is elastically pre-stressed against the attachment device to provide a retention force for the attachment device so as to resist undesired pivoting movement.
