Patent number: 7538285Abstract: An electrical device is disclosed for use in a wall box having a series of buttons that can either be rocker buttons or push buttons. These buttons can be supported by springboards formed integral with a support board. The springboards are for biasing the series of buttons. Much of the device is housed within a housing formed at a first end by a body and a second end by a strap coupled to the housing. The strap extends beyond the body, wherein this strap can be used to dissipate heat from the device. Inside of the housing can be at least one circuit board which has switches, which can be used to receive instructions from a plurality of buttons. In one embodiment, a plurality of light pipes are adapted so that they are housed at least partially inside of these buttons. At least one portion of the light pipe can be formed as a shaft and adapted to extend out from this housing and down to a light emitter disposed on the circuit board.Type: GrantFiled: March 30, 2007Date of Patent: May 26, 2009Assignee: Leviton Manufacturing Company, Inc.Inventors: Parimal Patel, Alfred F.

Publication number: 20090102677Abstract: A remote control electrical device which can communicate with a remote control device. The electrical control device is adapted to fit into a housing which fits into a wall mounting. The remote control electrical device can comprise a control circuit disposed in the housing, a transmitter disposed in the housing, a receiver disposed in the housing wherein said transmitter and said receiver are in communication with the control circuit. There is also a support plate having an inside face facing into the housing and an outside face facing away from the housing body. The support plate is coupled to the housing, wherein there is also an antenna disposed on the outside face of the support plate. This antenna does not receive any power-line AC frequencies or DC, instead it is capacitively coupled to the rest of the electrical components and disposed on the outside face of the support plate.Type: ApplicationFiled: November 14, 2006Publication date: April 23, 2009Applicant: LEVITON MANUFACTURING COMPANY, INC.Inventors: Parimal PATEL, Warren GUTHRIE, Danilo ESTANISLAO

Publication number: 20070109061Abstract: An aspect of the present invention is a voltage controlled oscillator that provides multi octave band tenability. The oscillator preferably includes one or more multi planar resonators which allow it to be implemented in integrated circuit form. Oscillators implemented in accordance with the aspect of the present invention provide as wide a tuning range as the YIG based resonators but are much more compact and efficient. Therefore, they are amenable to implementation in integrated circuits and suited for adaptation in third and future generation wireless devices.Type: ApplicationFiled: November 15, 2006Publication date: May 17, 2007Applicant: Synergy Microwave CorporationInventors: Ulrich Rohde, Ajay Poddar, Klaus Schoepf, Parimal Patel

Publication number: 20060240878Abstract: A cordless telephone outlet device that not only provides the cordless telephone access to a telephone network, but also provides the cordless telephone the proper DC electrical energy for proper operation eliminating the need for an unsightly external DC power supply typically connected to an AC outlet. Further, the device significantly reduces exposure of the telephone line connection between the cordless telephone and the telephone network. The outlet device comprises a body having a communications connector mounted thereon and a base attached to the body. The base contains DC power supply circuitry that is connected to a source of AC electrical energy. The output of the power supply circuit is connected to a DC line terminated with a DC male plug.Type: ApplicationFiled: June 30, 2006Publication date: October 26, 2006Inventors: David Eckel, Maxim Laurent, Parimal Patel

Patent number: 5218528Abstract: An automated voting system that integrates the stages of registering and certifying voters and collecting their votes. A computer-based voter registration station accesses a database to verify that the voter is eligible to vote. Vote entry stations provide a computer-based interactive graphic interface for permitting the voter to enter votes. A vote entry controller activates and monitors the vote entry stations to prevent unauthorized voting. Votes may be collected at either the vote entry stations or at the vote entry controller to which they are downloaded, which enhances security by providing a means to compare votes collected at one point in the system with votes collected at another point.Type: GrantFiled: November 6, 1990Date of Patent: June 8, 1993Assignee: Advanced Technological Systems, Inc.Inventors: George E. Wise, Parimal A. Patel, Clement L. Howe, William P. Spiers
