The control circuit 11 causes display of messages received through the communication unit 1 in the display unit 14 in list form. A cursor for making elections from the messages displayed in list form has different patterns. The control circuit 11 associates the cursor patterns with message types. In another embodiment, the control circuit 11 groups received messages into new messages not yet reproduced by a user and old messages already reproduced, causes display of the number of the new messages in a predetermined area of the display unit when the new messages are stored in RAM 13, and display of the number of the old messages in said predetermined area when the new messages are not stored in RAM 13.

A reliable method and apparatus for illuminating and imaging eyes uses multiple light sources producing multiple images of a subject each created under illumination by different illuminators. A composite image of the subject is formed by selecting pixels based upon their gray scale values or using pyramid image processing. A composite image can be created which is free of bright spots commonly caused by reflection of illumination from eyeglasses that may be worn by a subject or for which is free of dark shadows or which is free of both bright spots and dark shadows.

The magnetic-drive assembly (40) has an axial bearing which is strategically located to minimize compressive forces on a primary shaft (14). The axial bearing (55) functions both as an ordinary thrust bearing and an inefficient impeller for circulating fluid internally within the magnetic-drive assembly (40). The axial bearing (55) circulates lubricating fluid to a radial bearing to promote bearing longevity. The magnetic-drive assembly (40) has a shaft adjustment mechanism (42) for adjusting the axial orientation of a primary shaft (14) and impellers (22) with respect to a housing (12). The shaft adjustment mechanism retains its fixed axial orientation despite exposure to vibration and shock produced by the pump.

Mechanical complexity and high cost in a fuel control system for an engine (12) are avoided through the use of a pulse width modulated (PWM) valve (20) to meter a fuel flow to the inlet (50) of a fuel pump (16) that pumps the metered flow to an engine (12). The system utilizes a pulsating vapor core in the fuel pump (16) to dampen the pulses in the fuel flow generated by the PWM valve (20). A regulator valve (22) is provided to maintain a relatively constant pressure drop across the PWM valve (20).

An electric power generating system comprises a switched reluctance machine (10), an inverter (18) having a dc input/output coupled to a dc bus (24), switches responsive to switching control signals for coupling each of the machine's phase windings to the dc bus (24). A controller (22) having a number of control inputs and outputs coupled to the inverter (18) monitors the current flowing in the phase windings and voltage level on the dc bus (24) and calculates a maximum and a minimum phase current control signal. The controller (22) modulates the switching control signals to regulate the phase current within a range defined by these control signals to maintain the voltage level at a desired level. Upon calculating a positive phase current control signal, the controller (22) generates switching control signals to enable switches at a fixed angle prior to alignment, and generates switching control signals to disable the switches at a fixed angle after alignment. In this way, the machine generates sufficient electric power to maintain the voltage level at the desired level. Upon calculating a negative phase current control signal, the controller (22) generates switching control signals to enable the switches at a fixed angle prior to alignment, and generates switching control signals to disable one switch at a fixed angle prior to alignment. In this way, the machine (10) dissipates sufficient electric power to maintain the voltage at the desired level.

A damper comprises a cylinder (4) having an outer surface (15); a piston rod (2) slidably received in the cylinder (4); and a strut case (14) attached to the piston rod (2) and acting on the outer surface (15) of the cylinder to maintain the alignment of the piston rod (2) with the cylinder (4). An intermediate tube (20) is located between the cylinder (4) and the case (14) such that an inner surface of the intermediate tube (20) engages the outer surface (15) of the cylinder (4) and an inner surface of the case (14) engages an outer surface (22) of the intermediate tube (20). The intermediate tube (20) allows the damper to be extended in a telescopic manner such that the maximum travel distance of the damper is increased.

A variable valve timing device according to the invention includes a rotation shaft and a rotation transmitting member rotatably mounted thereon. The device takes a locked condition and an unlocked condition when a locking pin (60) is inserted into and disengaged from a receiving bore (32) formed in the rotation shaft, respectively. To disengage the pin (60) from the receiving bore (32), a fluid is supplied to the base of the receiving bore (32) from an independent fluid passage (13).
摘要:
A receiver for acquisition and lock of an impulse radio signal comprising an adjustable time base to output a sliding periodic timing signal having an adjustable repetition rate, and a decode timing modulator to output a decode signal in response to the periodic timing signal. The impulse radio signal is cross correlated with the decode signal to output a baseband signal. The receiver integrates T samples of the baseband signal and a threshold detector uses the integration results to detect channel coincidence. A receiver controller stops sliding the time base when channel coincidence is detected. A counter and extra count logic, coupled to the controller, are configured to increment or decrement the address counter by a one or more extra counts after each T pulse is reached in order to shift the PN code modulo for proper phase alignment of the periodic timing signal and the received impulse radio signal.

The discriminating circuits (158) generate a protection signal (160) in response to one of the magnitudes of the sequential half wave voltage signals being less than a threshold.
