Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.

Abstract: A downhole seal system for roller cone drill bits includes a seal gland having a width larger than it depth. In one implementation, the seal gland includes a protrusion along its base on which a seal element seats. The seal element is a single, annular seal element with a recess formed therein so as to define two lobes. The seal element seats in the gland so that the recess engages the protrusion. The lobes function as separate seal elements, although they are a single unitary seal element disposed in a single gland.

Abstract: According to one embodiment, the disclosure relates to a roller cone drill bit including a bit body having at least one support arm extending therefrom, a cone assembly containing bearings or retaining balls and rotatably mounted on a journal extending from each support arm, a lubricant reservoir disposed in each support arm, a lubricant chamber disposed in each support arm and fluidly coupled to the bearings or retaining balls, a bore disposed in each support arm to communicate lubricant between the lubricant reservoir and the lubricant chamber, and a pressure release mechanism disposed within the bore. The pressure release mechanism may be operable to relieve lubricant from the lubricant reservoir into the lubricant chamber when lubricant pressure within the lubricant reservoir exceeds pressure of the lubricant in the lubricant chamber. According to another embodiment, the disclosure relates to methods of relieving lubricant in such a bit.

Abstract: A disk drive is disclosed wherein during a first boot operation, first boot data is transmitted from a first plurality of data sectors to a host, and a first log identifying the first plurality of data sectors is maintained. During a second boot operation, second boot data is transmitted from a second plurality of data sectors to the host, and a second log identifying the second plurality of data sectors is maintained. During a third boot operation, data sectors identified by the first and/or second logs are pre-fetched into a cache.

Abstract: A conventional, stainless-steel acupuncture needle for use with a motor driven needling device for treating patients is provided with a thin, well-adhering, fluorocarbon-based coating. The coating is preferably implemented as a vapor phase coating, formed in a vacuum, to develop a tightly adhering, thin film coating over the surface of the needle. The coated needle is then coupled with the motor driven needling device, and inserted into the skin and muscle tissue of the patient. The motor driven needling device is then operated to cause the coated needle to reciprocate in the tissue of the patient for purposes of treating chronic muscular pain.

Abstract: A motor driven needling device for treating patients having chronic muscular pain includes a motor driven poking tool for mounting a needle, a control unit for adjusting the frequency and the depth of the poking, a mechanical swivel arm for holding and positioning the tool, a remote switch for activating the motorized tool, and an aid useful in causing the needle to puncture the patient's skin once the tool is positioned at a proper location over the muscle to be treated.

Abstract: A motor driven needle-poking device for treating patients having chronic muscular pain. The device consists of a motor driven poking tool for mounting a needle, a control unit for adjusting the frequency and the depth of poking, a mechanical swivel arm for holding and positioning said tool, and a remote activation switch for activating the motorized tool. Once the tool is positioned at a proper location of patient's skin by said swivel arm and activated by said switch, the needle pokes the muscle of interest underneath the skin at a constant frequency and at a fixed depth.

Abstract: A flash EEPROM is produced comprising multiple MOS cells. In each cell, programming and erasing are performed through tunneling from the write gate to the floating gate and by tunneling from the floating gate to the erase gate, respectively. The directional dielectric employed is a multilayered structured (MLS) oxide, where thin oxide and thin polycrystalline silicon form alternating layers. The layering is asymmetric: that is, either the uppermost or bottommost layer is thicker than the other layers. As a result of this structure, the oxide exhibits directionality, that is, the tunneling is easier in one direction than the reverse direction, and significantly enhances the tunneling phenomena (tunneling current can be observed at as low as 4.7 V). In addition, the MLS oxide can be fabricated having different dielectric constants.
