Patent number: 9010140Abstract: A system for reducing idle time in service vehicles such as police patrol cars. A bank of auxiliary batteries is provided. An electrically-powered auxiliary air conditioning compressor is also provided. The auxiliary air compressor is connected to the discharge and suction lines of an existing an conditioning system so that it can propel refrigerant through an existing refrigerant circulation loop. When the vehicle's internal combustion engine is switched off, the auxiliary batteries are selectively used to power the auxiliary air-conditioning compressor in order to provide cooling for the vehicle's cabin. The auxiliary batteries are also used to provide electricity to the vehicle's other electrical loads—such as emergency lights.Type: GrantFiled: February 15, 2013Date of Patent: April 21, 2015Assignee: City of TallahasseeInventor: Jonathan W. Cook

Patent number: 8997510Abstract: A solar powered compressor and pump is disclosed having a trough-shaped parabolic reflector for heating a conduit of refrigerant as it passes through the system. The compressor/pump combination includes a lens that covers the reflector and insulates and protects the reflector from the elements while increasing the intensity of the sun's energy entering the reflector. The reflector converts the sun's energy into heat that superheats the refrigerant as it passes through the reflector, reducing or eliminating the amount of mechanical work that the system has to do to achieve the needed superheating stage.Type: GrantFiled: March 10, 2010Date of Patent: April 7, 2015Inventor: Craig McKenzie

Patent number: 8996214Abstract: A hybrid working vehicle comprises an engine, a drive wheel, a power take-off (PTO) shaft, and a power transmission system for transmitting power from the engine to the drive wheel and the PTO shaft. The power transmission system is bifurcated at a bifurcating point into a traveling drive train for driving the drive wheel and a PTO drive train for driving the PTO shaft. A continuously variable transmission is provided on the traveling drive train, and a motor generator is provided on the power transmission system between the engine and the bifurcating point. The motor generator functions as a generator by power of the engine and functions as an electric motor for driving the power transmission system. The hybrid working vehicle includes a controller for controlling an output rotary speed of the motor generator functioning as the electric motor.Type: GrantFiled: August 31, 2012Date of Patent: March 31, 2015Assignee: Kanzaki Kokyukoki Mfg. Co., Ltd.Inventor: Norihiro Ishii
