Abstract: Embodiments of a system and method are described. These embodiments may be designed to provide alert to a law enforcement officer monitoring a signalized roadway intersection. In particular, the embodiments comprise a transmitting unit installed in an intersection control cabinet and a radio frequency (RF) remote receiving unit. The transmitting unit comprises at least one cable harness, an on board power supply, a switching circuit, a first central processing unit, and a radio frequency (RF) transmitter. The RF remote receiving unit comprises an internal antenna, a second central processing unit, a battery pack, a power jack and a receiver switch. The RF remote receiving unit alerts the law enforcement officer on the at least one traffic signal information corresponding to red-light-running in a signalized roadway intersection. The at least one traffic signal information is imparted to the law enforcement officer utilizing at least one signal indicator.

Abstract: A battery protection device for disconnecting a plurality of batteries from an inverter to avoid excessive discharge. The device comprises at least one battery connector for connecting to the plurality of batteries, at least one inverter cable for connecting to the inverter, and a plurality of wires for connecting to an AC input. The device gets activated when the AC input to the inverter cuts off and continuously monitors a voltage level of the batteries. Further, the device automatically disconnects the batteries from the inverter at a preset voltage level and shuts itself off to achieve a protection mode wherein the device does not draw any current to avoid further drainage of the batteries. A voltage level of the device is set above a preset voltage for recharging batteries and when the AC input is restored, the device reconnects the batteries to the inverter.

Abstract: An interface system for use in a motor vehicle to be converted to a police or emergency vehicle includes a switch panel array operating an array of relays which in turn controls a lamp unit such as a conventional light bar. A video camera and VCR are mutually coupled to a VCR control which in turn responds to a control logic to provide automatic operation of the VCR during events. A canine alert system includes temperature sensing and engine electrical system sensing and responds to an air conditioning failure or engine stall condition to produce a transmitted alert signal using a pager or beeper or the like. A power management system monitors the operating supply voltage of the vehicle and sequentially shuts down the emergency light apparatus as the battery voltage decreases. A back-up light and brake light kill responds to a panel control switch for interrupting the activity of brake lights and back-up lights.
