  • Patent number: 8347533
    Abstract: Flexible indicia bearing labels are placed on armored electrical cable at spaced apart intervals while the cable is moving continuously from an armoring station to a takeup reel or accumulator. A label dispenser places labels in a U shaped recess of a body which is moveable toward engagement with the cable. Opposed rollers fold one edge of the label over into engagement with the surface of the cable and the other edge of the label over onto itself in overlapping relationship. The cable is passed through a heat tunnel to shrink the labels into tight engagement with the cable. A controller monitors movement of the cable and controls actuators for applying and folding labels onto the cable at spaced apart intervals.

  • Patent number: 8350622
    Abstract: A circuit includes a differential amplifier having a folded cascode architecture with a pair of cascode transistors. A sensing circuit senses a common mode input voltage of a differential input signal applied to the differential amplifier. A bias generator circuit generates a bias voltage for application to the pair of cascode transistors in the folded cascode architecture. The bias generator circuit is connected to an output of the sensing circuit such that the generated bias voltage has a value which is dependent on the sensed common mode input voltage. This dependence stabilizes a common mode output voltage from the differential amplifier in response to changes in the common mode input voltage.

  • Patent number: 8347275
    Abstract: To address a desire to run 3D applications based on the OpenGL standard on OpenGL|ES mobile devices such as cellular telephones, one must be able to translate function calls between OpenGL and OpenGL|ES. In supporting this translation, and so as to ensure proper data state for the continued execution of the OpenGL application, global GL states which might be changed by an OpenGL|ES function used during translation are stored. The OpenGL to OpenGL|ES translation is then effectuated by substituting appropriate OpenGL|ES commands for OpenGL commands, and passing OpenGL|ES APIs for OpenGL|ES implementation. Thereafter, the global GL states which were previously saved are restored such that the performed translation does not adversely impact continued execution of the OpenGL configured application. This translation process supports OpenGL to OpenGL|ES translation with respect to a number of OpenGL APIs as well as some known extensions.

  • Patent number: 8331570
    Abstract: The quality of music output from audio systems is improved by simulating the effect of low frequency signals in the human ear. This thus allows listeners to perceive the lower frequency signals, even though the speakers may be incapable of providing such low frequency outputs. Method and systems provided for processing enhancing bass effect in audio signals. Said method and systems result in the bass enhancement being computationally less intensive. The bass effect enhancement techniques described are based on the response of sine and cosine transfer functions and on the directional independence of low frequency components. The human ear is unable to resolve directions from low frequency components. The bass effect enhancement technique alternatively is based on response of an exponential transfer function.

  • Patent number: 8312805
    Abstract: A high pressure piston for use within a liner sleeve of a reciprocating pump comprises a dual-durometer elastomeric seal having first and second coaxial seal sections and, in certain embodiments, a circumferential bearing ring. Interactions of the seal components, including seal elastomers, result in stress redistribution within the seal which maintains sealing preload, with corresponding improved extrusion resistance and seal durability. When a bearing ring is present, a pump's pressure stroke causes at least a portion of the bearing ring to elastically expand radially to narrow or close the extrusion gap, thus tending to block elastomer extrusion by establishing sliding contact between the bearing ring's external surface and the liner. On the pump's return stroke the slightly wider extrusion gap allows cooling water directed generally toward the proximal flange of the piston hub to better cleanse, as well as cool, the liner wall.
