A wireless parking meter with an improved antenna location is described. The antenna may be located within a covering protruding from the top of the parking meter, allowing radio frequency (RF) signals to be transmitted through a portion of the parking meter with high permittivity to the RF signals. Additionally or alternatively, the antenna may be located within the parking meter housing above a lower parking meter mechanism housing so that RF signals can be transmitted through the dome covering of the parking meter, which may have a high permittivity to the RF signals.

Single space wireless parking with improved antenna placements

A parking meter with an antenna for radio frequency (RF) communication is provided. An antenna for the parking meter may be located in order to transmit the RF signals through a transmission path comprising at least a portion of the parking meter that provides a low attenuation of RF signals.

A proximity detector for detecting the presence of a coin or token in a coin chute, comprising a pair of axially aligned coils disposed on opposed sides of the chute; a common-emitter amplifier having a base and a collector providing a detector output, one of the coils being connected to the collector and the other of the coils being connected to the base.

Electronic parking meter

A lighting fixture and power supply are provided that allows a power factor correction (PFC) single ended primary inductance controller (SEPIC) that provides a controlled voltage output to provide a constant current to an LED load. The power supply provides an efficient and stable power supply for LEDs. Multiple power supplies can be provided on the same printed circuit board to control multiple LED channels.

Single-ended primary inductance converter (SEPIC) based power supply for driving multiple strings of light emitting diodes (LEDs) in roadway lighting fixtures

A method for identifying metallic coins and tokens, comprising: applying an input signal to an ac-bridge; bringing a coin/token in the vicinity of one arm of the ac-bridge; sensing an output signal of the ac-bridge; and associating the output signal with presence of the coin/token in the vicinity of the arm of the ac-bridge.
