  • Patent number: 9726844
    Abstract: In one aspect, a lighted tip for attachment to a flexible rod comprises a tip body having proximal and distal ends, a mechanical connector at the proximal end, a lens connected to the distal end, a light source that emits light through the lens, and a holder coupled to the light source and the lens. A circuit is completed or interrupted as the holder moves in relation to the tip body, thereby switching the light source on or off. In another aspect, a lighted tip for attachment to a flexible rod comprises a lens forming a distal end of the lighted tip. The lens is cylindrical over at least some of its length, and the tip further includes a light source at least partially within the cylindrical lens portion and a mechanical connector at a proximal end if the lighted tip, for connecting the tip to the flexible rod.

  • Patent number: 9004756
    Abstract: A temperature sensor includes a constant current source and a transistor stack connected to the constant current source. The transistor stack includes a first transistor having a base connected to the constant current source and a collector coupled to a supply voltage. The collector of the first transistor is electrically isolated from the base of the first transistor. The transistor stack includes a second transistor connected to the first transistor. The second transistor has a collector connected to an emitter of the first transistor and has a base connected to the collector of the second transistor. The transistor stack includes an output node disposed between the constant current source and the base of the first transistor. A voltage of the output node is indicative of a temperature.

  • Patent number: 8324064
    Abstract: Methods are disclosed for forming an improved varactor diode having first and second terminals. The methods include providing a substrate having a first surface in which are formed isolation regions separating first and second parts of the diode. A varactor junction is formed in the first part with a first side coupled to the first terminal and a second side coupled to the second terminal via a sub-isolation buried layer (SIBL) region extending under the bottom and partly up the sides of the isolation regions to a further doped region that is ohmically connected to the second terminal. The first part does not extend to the SIBL region. The varactor junction desirably comprises a hyper-abrupt doped region. The combination provides improved tuning ratio, operating frequency and breakdown voltage of the varactor diode while still providing adequate Q.

  • Patent number: 6225674
    Abstract: A semiconductor structure (10) having device isolation structures (43, 44) and shielding structures (39, 40). The shielding structures (39, 40) are formed in a semiconductor material (11) and the device isolation structures (43, 44) are formed within the corresponding shielding structures (39, 40). A noise generating device is formed within a first shielding structure (43) and a noise sensitive device is formed within a second shielding structure (44). The two shielding structures (39, 40) are grounded and prevent noise from the noise generating device from interfering with the noise sensitive device.
