Abstract: An efficient system for directing light comprises a light source and a generally tubular, hollow coupling device. The coupling device has an interior light-reflective surface for receiving light from the source at an inlet and transmitting it as a generally diverging light beam through an outlet. The device is shaped in accordance with non-imaging optics and increases in cross sectional area from inlet to outlet so as to reduce the angle of light reflected from the surface as it passes through the device.

Abstract: A support bracket for a device, such as a light, has a swivel mount provided at one end of a bent support arm, the other end of which can be held in a conventional stand. The support arm is shaped to position a light or other device connected to the swivel mount so that the center of gravity of the light is over the vertical axis of the stand. Positioning the center of gravity over the vertical axis of the stand is essential, so that the need for counterweights, counterbalances and ballasts is reduced in order to keep the light stable when mounted on the connector bracket held by a stand. When the center of gravity of the light is also aligned with a horizontal axis of the swivel mount bracket, the light can be pivoted and rotated on the bracket without affecting the balance. The tilt bracket is preferably used with portable lights so that the amount and weight of equipment needed to mount the light is reduced.

Abstract: A blender in the invention includes a handle at one side of a container and having a link rod disposed therein. A microswitch is in a base and an actuating rod is above the microswitch. The link rod has an upper end protruding into a slide groove of the handle and a lower end extending into a lower portion of the container and touched against the actuating rod.

When the cover is closed on the container, its push block is lowered to press the link rod down to force the actuating rod to be contacted with the microswitch to form an open electric circuit enabling the blender to work, thereby providing the blender with high security in use.

Abstract: A four current transistor temperature sensor comprises a p-n junction, preferably the base-emitter junction of a bipolar transistor, which is driven with four different currents in a predetermined sequence. Each of the four currents induces a respective base-emitter voltage, which is measured.

The four driving currents (I1, I2, I3 and I4) are preferably arranged such that I1=2*I3, I2=2*I4, I1/I2=A and I3/I4=A, where A is a predetermined current ratio. I1 and I2 produce respective base-emitter voltages which are subtracted from each other to produce &Dgr;Vbe1, and I3 and I4 produce respective base-emitter voltages which are subtracted from each other to produce &Dgr;Vbe2. When so arranged, the difference between &Dgr;Vbe1 and &Dgr;Vbe2 is entirely due to the effect of series base and emitter resistances rb and re.
