摘要:
A flashlight has a lamp, a power source, two switches, and a controller connected to the switches. The first switch controls delivery of power to the lamp, and the second switch selects a dimmed brightness level. The first switch may invoke the dimmed level, or a maximum brightness level. The second switch may be a ring rotatable about the axis the flashlight, and either rotatable through a wide range of positions, with sensor circuitry to detect the absolute position, or having a limited range of rotation, with dimmed level selection provided by a duration of momentary rotation in either direction. The second switch may be positioned outside a leak resistant housing, and may include a magnet detectable by magnetic field sensors within the chamber.

Flashlights having selectively controllable brightness levels, a preferred embodiment of which comprises in combination: a battery; a light emitter assembly; a switch in circuit with the battery and the light emitter assembly, the switch having a first OFF position and a second OFF position, the first ON position coupling the battery to the light emitter assembly for producing a first light output, and a second ON position coupling the battery to the light emitter assembly for producing a second light output; and a switch actuator adapted to be coupled to the switch alternatively in its first OFF position and its second OFF position, the switch actuator when coupled in its first OFF position is translatable by a first distance placing the switch in its first ON position and translatable by a second distance placing the switch in its second ON position, the switch actuator when coupled in its second OFF position is translatable by a third distance placing the switch in its first ON position. The switch actuator preferably comprises a click-ON/click-OFF pushbutton switch actuator, for alternatively placing the switch momentarily in its first and second ON positions and constantly in its second ON position from its first OFF position; and for alternatively placing the switch momentarily and constantly in its first ON position from its second OFF position.

A flashlight has a lens having an optical axis, with a first light source positioned on the optical axis. A second light source is spaced apart from the first light source away from the optical axis, and the lens has an aperture registered with the second light source. The lens may have a central portion configured to transmit axially-emitted light from the first light source, and the lens having a peripheral portion having an internally reflective surface configured to reflect laterally-emitted light from the light source in a direction more closely aligned with the optical axis. The first light source may be positioned within a recess in the lens, and the aperture may be formed in the peripheral portion of the lens. The light sources may be LEDs, and may be of different colors.

An accessory mount for a firearm having a longitudinal barrel, a first support and a second support forwardly of the first support. The accessory mount includes a first longitudinal mount housing having a rear portion, the first housing positionable along the barrel with its rear portion supported by the first support; a second longitudinal mount housing having a rear portion, the second housing positionable along the barrel with its rear portion supported by the second support; longitudinal grooves in one of the housings, and longitudinal flanges on the other of the housings slidably received by the channels and transversely securing the housings together; and at least one adjustable member carried by one of the housings and cooperating with the other of the housings for urging the housings in longitudinally opposite directions, preferably with the rear portion of the first housing rearwardly urged against the first support and with the rear portion of the second housing forwardly urged against the second support.
摘要:
A receiver for receiving information that contains clock information and data information and a clock-embedded interface method. In the clock-embedded method, a clock signal and data may be reconstructed by receiving a pair of differential signals that contain clock information and data information and by using a change in a common voltage of the pair of differential signals.

The present invention relates to a device and method for measuring a three-dimensional shape and, more particularly, to a measurement device and method in which a specific pattern is generated on the surface of an object to be measured, the object is photographed using a camera, and data on the 3-D shape are acquired from a photographed image, wherein an irregular pattern is employed, thus simplifying a process of measuring the 3-D shape. The present invention is suitable for the measurement of a moving object, the fabrication of the device can be easily performed, various pattern generation means can be utilized, and an inexpensive and popularized image camera can be used instead of an expensive industrial camera. The present invention can be applied to the fabrication of custom-made shoe soles and custom-made shoes and a medical field.
