Abstract: A security arrangement includes a mounting device having an upstanding wall. The mounting device is mounted to a surface of a structure such that the wall is oriented substantially perpendicular to the surface. A security sensor senses an event that occurs outside of the security arrangement. A tamper detector is attached to the security sensor and includes an optical emitter, an optical receiver, and a slot disposed between the emitter and the receiver. The emitter transmits optical energy that is received by the receiver through the slot. The wall of the mounting device is received in the slot when the tamper detector is coupled to the mounting device to thereby block the transmission of the optical energy from the emitter to the receiver. A controller is communicatively coupled to the receiver and produces a tamper signal in response to the receiver receiving the optical energy.

Abstract: A method and system for controlling a home automation system by voice input provided via a telephone unit. A voice portal server receives a signal transmitted by the telephone unit, processes the signal to interpret the voice input, and generates command signals for controlling a home device in the home automation system based on the interpreted voice input. The voice portal server transmits the command signals over a data network or a telephone network to a home interface for receiving the command signals transmitted by the voice portal server. The home interface controls the home device in accordance with the received command signals.

Abstract: A fuel injection valve (1) configured such that control of the escape of high-pressure fuel inside a control chamber (45) to a fuel low-pressure portion is conducted by an electromagnetic valve (5) for controlling fuel injection configured such that a lift operation of an armature plate (51) is controlled by an electromagnetic solenoid (68) and an armature stopper (67) incorporated inside a fixed sleeve (61), wherein a gap (G3) is disposed between a fixed core (63) and the armature stopper (67), through holes (67B) are disposed in the armature stopper (67), and drain fuel flows to the fuel low-pressure portion via the gap (G3) and the through holes (67B) when the electromagnetic valve (5) is powered. As a result, the lift amount of the armature plate (51) can be prevented from changing as a result of debris or the like included in the drain fuel becoming caught between the armature plate (51) and the armature stopper (67).

Abstract: An exhaust emission purifying apparatus for an engine, which is provided with: an electric pump sucking and supplying a liquid reducing agent by pumping out of a reducing agent tank; a flow control valve controlling flow rate of the liquid reducing agent; and an injection nozzle injection-supplying the liquid reducing agent with the controlled flow rate, to an exhaust emission upstream of NOx reduction catalytic converter. At the engine starting, a highly pressurized air is urged to reversely flow to a reducing agent supply system upstream of the flow control valve. Then it is determined whether or not the reducing agent supply system brings about clogging based on a pressure change produced by the reverse flow. When a number of frequency at which it is consecutively determined as occurrence of clogging reaches a predetermined number or more, it is determined that the clogging is serious, which is unable to be readily mended.

Abstract: The invention is directed to improvements to the assembly of a unitized spring device. The spring device comprises a pair of retainer members which are tubular in shape and hollow inside. The retainer members have different outer circumference diameters which allow the second retainer member to fit onto the outer circumference of the first retainer member. The first retainer member has a first outward claw portion at one end and the second retainer member has a second inward claw portion at one end, such that the second claw portion can move beyond the first claw portion to couple the first and second retainer members in the axial direction. These first and second claw portions prevent one another from being pulled out in the coupled state. The first retainer member also comprises a slit which extends in the axial direction and divides at least the side having the first claw portion.

Abstract: An appropriate recovery process is made possible according to the situation of a power supply anomaly. When a system reset occurs, a storage unit stores an operation state of a system immediately before the reset in an operation state memory and also stores a recovery mode determined according to the stored operation state in a recovery mode memory. At the beginning of the recovery process, a necessary process is performed according to the stored recovery mode. Each time the recovery process is performed, a recovery counter performs enumeration and a normal-operation-time timer counter enumerates a normal operation time of the system. Such processes as a system halt and an engine recovery are performed according to the enumerated value and the normal operation time enumerated by the counters.

Abstract: An actuator for a drum brake including a plunger connected through a resilient member to a linkage attached to a web on a brake shoe. A rod extends from the plunger and engages a lever arm that is pivotally retained on the web. The lever engages an extendable strut of an adjuster arrangement through which a running clearance is maintained between the brake shoe and a drum. During a brake application, pressurization fluid acts on the plunger to develop an operational force that is communicated through the resilient member to move the brake shoe into engagement with a drum. Should the operational force overcome the resilient member, the plunger moves toward the linkage and a reactive force is applied through the rod that acts through the lever arm to prevent a pawl from rotating such that a current length of the strut and correspondingly a current running clearance is sustained.

Further, a drive current (Y) necessary for thermal-maintenance is supplied to a heater (17A) in response to an output signal (S3) from the selecting part (50).

Abstract: In the DME fuel supply device for a diesel engine, the time necessary to retrieve DME fuel remaining in the injection system after stopping the diesel engine into the fuel tank can be reduced. In a non-injection state, a three-way valve (71) is controlled to be OFF to form a communication passage in the direction indicated by the arrow B and a two-way valve (72) is controlled to be ON. DME fuel delivered from a feed pump (5) is delivered to an aspirator (7), passed from an inlet (7a) to the outlet (7b) thereof and returned to a fuel tank (4). That is, the DME fuel circulates via the aspirator. A vapor-phase pressure delivery pipe switching solenoid valve (75) is controlled to be ON and opened so that flow can pass through a vapor-phase pressure delivery pipe (73) connecting the vapor-phase (4a) in the fuel tank (4) and the inlet of the fuel gallery (11).

Abstract: A disc brake has a first caliper with first and second friction members that are moved into engagement with a rotor to effect a brake application. The actuator includes a second caliper retained on a pin and third and fourth friction member aligned with the rotor. First and second linkage members connect the second caliper to the first and second friction members. The second caliper when activated moves the third and fourth friction members into engagement with the rotor to create a tangential force that causes the second caliper to pivot on the pin and provide an input force that moves first and second ramp surfaces on the first and second linkage members to produce an actuation force that moves the first and second friction members into engagement with the rotor to produce a braking force that retards the rotation of the rotor.
