Abstract: A parking meter detects an object in proximity, based on a change in a proximity measurement at the meter, activates a directional sensor in response to detecting the object, receives sensor data at a meter processor from the directional sensor, wherein the received sensor data indicates a predetermined direction to the detected object relative to the meter. The parking meter determines a presence of the object, or lack thereof, in the predetermined direction based on the sensor data, and upon a positive determination of the presence of the object, stores an indication of the presence of the object along with a time of the positive determination.

Abstract: Devices and meters comprising: a housing configured to mount to a pole supporting an existing meter, the housing defining an interior; a sensor within the interior of the housing, the sensor configured to collect environmental information pertaining to the local external environment of the existing meter; a wireless radio within the interior of the housing, the wireless radio configured to transmit the environmental information to the existing meter or to a remote server in communication with the existing meter; a power unit within the interior of the housing, the power unit supplying power to the sensor and the wireless radio.

Abstract: A power supply unit for supplying power to a device has a rechargeable, main battery; a charging arrangement for charging the main battery; a non-rechargeable back-up battery; load terminals for connection to a load; and a control unit for controlling supply of power to the load primarily from the main battery and secondarily from the back-up battery. The device is, in particular, a single bay, stand alone parking meter. In the event that the main battery runs low, the control unit is configured to supply power to the load from both the main battery and the back-up battery or only from the back-up battery. The back-up battery is easily replaceable, and the power supply unit has a bay, with connectors for receiving the back-up battery. The main battery is charged from solar panels. A communication device is provided to communicate status messages wirelessly to a control system.
