Abstract: A real-time wireless parking enforcement system is provided that includes a remote parking enforcement system having a plurality of parking sensors disposed to gather parking occupancy data and at least one source of parking payment data, where the parking occupancy data and parking payment data is communicated to a central server in real-time, and a plurality of wireless mobile platforms are operated by a plurality of parking enforcement officers (PEO's). The wireless mobile platforms send and receive real-time and continuous parking occupancy data and parking payment data to and from the central server, where bidirectional communication exists between the central server and the wireless mobile platforms. When the PEO enters response information to a potential violation to the wireless mobile platform, the bidirectional communication updates the status of the potential violation to all the wireless platforms in real-time, where the information is used to reduce enforcement redundancies by the PEO's.

Abstract: In one aspect, the invention provides semiconductor sensor which includes a first single crystal silicon wafer layer. A single crystal silicon structure is formed in the first wafer layer. The structure includes two oppositely disposed substantially vertical major surfaces and two oppositely disposed generally horizontal minor surfaces. The aspect ratio of major surface to minor surface is at least 5:1. A carrier which includes a recessed region is secured to the first wafer layer such that said structure is suspended opposite the recessed region.

Abstract: A method for detecting the condition of the individual cells of a bank of serially connected battery cells is provided. The method utilizes a single common sensing wire connected through respective non-linear component switching mechanisms to respective reference terminals. The reference terminals are located between adjacent batteries and at the end of the battery assembly. The method includes the step of detecting an instantaneous change of impedance at points of transition of the state of the individual switches provided.
