Abstract:
Disclosed are carrier compositions for electrophotographic developers comprising core particles coated with a mixture of a resin and an organic surfactant having at least one carbon-fluorine bond and at least one functional group having an affinity for the resin. An intermediate resin layer may be present on the core particles, which themselves may be metal, glass or silicon dioxide, e.g.
Abstract:
A method and apparatus are presented for inductive charging of battery operated devices in a motor vehicle, in which a passive vehicle entry and/or starting system selectively disables or reduces provision of power to a primary coil of an inductive charging station while the passive system communicates with an external user device such as a key fob controller to avoid or mitigate electromagnetic interference.
Abstract:
A vehicle entry/tire pressure management system includes an ECU, tire sensors mounted in, on or adjacent respective tires of the vehicle, a portable transmission/reception unit configured to be carried by an operator of the vehicle, and an antenna mounted on the vehicle and in communication with the ECU. Each tire sensor is configured to transmit an RF signal. The portable transmission/reception unit can transmit RF signals for controlling operations of the vehicle including unlocking doors of the vehicle. The antenna is configured to transmit an LF tire sensor wake up field to wake up the tire sensors. The tire sensor wake up field includes a unique header format. The tire sensors only fully wake up upon receiving the unique header format.

Abstract:
A method for disabling a passive entry key includes receiving a search request into an electronic control unit (“ECU”) on a vehicle to search for a passive key inside a vehicle cabin; emitting a search signal via an antenna in communication with the ECU in response to the received search request; receiving a reply signal via the antenna from the passive key inside the vehicle cabin; and recording in a memory in communication with the ECU an identification of the passive key inside the vehicle cabin in response to the received reply signal. In this method for disabling a passive entry key, the search request can be initiated by an operator at an input device. A passive entry key system is also disclosed.
Abstract:
A keyless function system and method includes a portable device having a vehicle function actuator thereon for initiating operation of a vehicle function. The portable device transmits an actuation signal to the vehicle when the vehicle function actuator is actuated. The receiver onboard the vehicle receives the actuation signal from the portable device. A controller onboard the vehicle and operatively connected to the receiver determines at least one of: whether the vehicle is located at a predetermined location or whether the portable device is located less than a predetermined distance from the vehicle. The controller selectively commands performance of the vehicle function when the actuation signal is received by the receiver based on at least one of: whether the vehicle is at the predetermined location or the portable device is less than the predetermined distance from the vehicle.
Abstract:
In a keyless entry system, a CPU in an ECU and a CPU in a remote control key change a function formula specified by primary function formula data stored in a memory and a function formula specified by primary function formula data stored in a memory to respective new function formulas. With this structure, function formulas used in the remote control key and the ECU can be changed to respective new function formulas. This makes it possible to enhance the safety of the keyless entry system because it is difficult to predict the function formulas used in the remote control key and the ECU.
Abstract:
A vehicle door outer handle system includes: an operating handle formed from a handle main body and a cover covering the outer side of the handle main body; a pair of electrodes; and a circuit board on which a detection circuit is provided for detecting a change in capacitance between the electrodes; the electrodes and the circuit board being housed within the operating handle. The electrodes are patterned on the circuit board, and a ground pattern connected to the detection circuit is formed so as to be disposed at a position offset from the electrodes if viewed through the circuit board.
Abstract:
In the optical multiplexer/demultiplexer according to the invention, an MMI (multi mode interference) coupler having a percentage coupling of about 50% is used as first and second optical couplers, and a directional coupler having a percentage coupling of less than 10% is used as third and fourth optical couplers. By virtue of this constitution, the optical multiplexer/demultiplexer according to the invention has a small dependency upon wavelength and can be used in a wide waveband, is less susceptible to a preparation error, and, at the same time, has good wavelength flatness in passband and a wide rejection band.
Abstract:
There is provided a generator system for internal combustion engines, which can produce power efficiently at all times irrespective of the engine speed even for use in an internal combustion engine operated at variable speeds such as a vehicle engine. An AC generator electronic control unit (ACG.ECU) 3 determines a rotation speed N2 of a rotating electromagnetic field to be generated by a rotor 1R based on a mechanical rotation speed N1 of the rotor 1R in an alternator 1 such that the relative speed N of the rotating magnetic field to a stator 1S agrees with the maximum efficiency speed of rotation Nx. Then the ACG.ECU 3 sends the determined value to a rotating electromagnetic field controller 2a. The rotating electromagnetic field controller 2a controls phases of AC power to be supplied to a three-phase coil 11 of the rotor 1R to generate a rotating electromagnetic field with the rotation speed N2.
