Abstract: A sensing apparatus for characterizing current flow through a conductor includes a plurality of magnetic sensors. In some embodiments, the sensors are grouped in pairs to achieve common mode rejection of signals generated in response to magnetic fields not resulting from current flow through the conductor. Sensors having different levels of sensitivity are used to collect information regarding the magnetic field generated by the current flowing through the conductor, where such information is processed in order to characterize the magnetic field. In some cases the sensors are included on or in flexible material that can be wrapped around the conductor.

Abstract: A seat assembly is provided with a seat bottom, a seat back, and a plurality of sensors operably connected to at least one of the seat bottom and the seat back to detect a seating condition of a seated occupant. A controller is in electrical communication with the plurality of sensors and the at least one actuator. The controller is programmed to receive input from the plurality of sensors indicative of a seating condition of the seated occupant. The seating condition of the seated occupant is compared to stored seating conditions of prior seat occupants to determine that the seated occupant is a prior occupant.

Abstract: Apparatus and methods for the collection, processing, storage, communication and use of data generated by an array of sensors connected to a body for the purposes of monitoring and measuring sequences of body structural motion (exercises). This training and feedback may be used to aid in the development of specific muscle memory for specific actions. Analysis of the collected data is employed to aid the user in accomplishing more efficient and effective physical training. Data may also be used by 3rd parties to monitor performance and update training regimes.

Abstract: Apparatus and methods for the generation, collection and use of specific user-induced motions of an appliance device and the use of the correspondence between these collected measures of user-induced motions and previously generated and possibly stored measures of user-induced motions of an appliance device are provided. This system includes methods for generating the stored measures of user-induced motions and for continuously updating these stored references.

Abstract: A method and apparatus for interconnecting circuit portions (12, 14, 16, 18, 20) within a data processing system (10) using a master/slave interfaces (30–37, 134) which may be configured by way of configuration registers (21–28, 156, 100). External address generation circuitry (140) and internal address generation circuitry (142) may be used to generate externally used addresses and internally used addresses, respectively. A circuit portion (e.g. 20) may have a plurality of interfaces (37, 134) which may operate as a slave interface (e.g. 134) or as a master interface (e.g. 37). A same master/slave interface structure and protocol (e.g. 30, 140, 142, 144, 28, 152) may be duplicated and individually configured to be used to communicate among all of the circuit portions (12, 14, 16, 18, 20) within a data processing system (10).

Abstract: A voltage generation circuit (60, 62) is adapted to sense voltages on multiple windings (82, 84, 86) of a multi-phase brushless DC motor (22) during successive intervals of a rotation of the motor (22) in which the respective windings (82, 84, 86) are not being driven. The voltage generation circuit (60, 62) provides a different output voltage from the voltage used to drive the motor (22). In one embodiment, the voltage generation circuit (60, 62) includes a voltage boosting circuit (62) to increase the output voltage above the drive voltage. This voltage generation circuit (60, 62) may be advantageously combined with an electrically programmable read only memory (EPROM) (56) on a single integrated circuit chip. The voltage generation circuit (60, 62) generates the EPROM programming voltage without the need for a costly on-chip charge pump or off-chip DC-DC converter.
