An LDMOS transistor and a bipolar transistor with LDMOS structures are disclosed for suitable use in high withstand voltage device applications, among others. The LDMOS transistor includes a drain well region 21 formed in P-type substrate 1, and also formed therein spatially separated one another are a channel well region 23 and a medium concentration drain region 24 having an impurity concentration larger than that of drain well region 21, which are simultaneously formed having a large diffusion depth through thermal processing. A source 11s is formed in channel well region 23, while a drain 11d is formed in drain region 24 having an impurity concentration larger than that of drain region 24. In addition, a gate electrode 11g is formed over the well region, overlying the partially overlapped portions with well region 23 and drain region 24 and being separated from drain 11d. Since the source 11s, well region 23, and drain region 24 are respectively self-aligned to the gate electrode 11g, resultant transistor characteristics are stabilized, and the decrease in the on resistance and improved drain threshold voltages can be achieved. Also disclosed herein are bipolar transistors with LDMOS structures, which are capable of obviating the breakdown of gate dielectric layers even at high applied voltage and achieving improved stability in transistor characteristics.

Direct optical imaging of anatomical features and structures from within a biological organ in a dynamic environment (where the tissue being imaged is in motion due to cardiac rhythms, respiration, etc) presents certain image stability issues due (and/or related) to the motion of the target structure and may limit the ability of the user to visually interpret the image for the purposes of diagnostics and therapeutics. Systems and mechanisms for the purpose of actively stabilizing the image or for compiling and re-displaying the image information in a manner that is more suitable to interpretation by the user are disclosed.

An implant insertion system includes a shape memory implant movable between a first shape a second shape and an implant insertion device movable between an implant disengagement position and an implant engagement position. The implant insertion device receives the shape memory implant in its first shape while in its implant disengagement position. Movement of the implant insertion device from its implant disengagement position to its implant engagement position manipulates the shape memory implant from its first shape to its second shape. The implant insertion device maintains the shape memory implant in its second shape until delivery of the shape memory implant into tissue or bone.

An implantable medical device is provided which has a housing of an elongate form to minimize a size of an incision required for implantation. A stabilizing element is associated with the elongated form housing for the medical device. The stabilizing element transitions from a low profile initial form to a higher width final form to provide the medical device with a stabilized footprint after implantation. The stabilizing element is in the form of a rotating wing in one embodiment. In another embodiment, the stabilizing element is in the form of an expanding loop that can bend to extend out of side openings of a cavity within the housing, to provide such stabilization at the implantation site. The medical device can be in the form of a pacemaker, infusion pump, vascular access port or other subcutaneously implanted medical device.

A semiconductor device such as an RFID, which can easily generate a given stable potential, is provided. Circuits included in a semiconductor device are categorized depending on whether a given stable power source potential is necessary. A power source potential generated from a wireless signal received by an antenna with the use of the antenna and a rectifier circuit is supplied to a circuit which needs a given stable power source potential through a regulator. On the other hand, a power source potential generated by the rectifier circuit is supplied to a circuit other than the circuit which needs the arbitrary power source potential. Thus, a semiconductor device including a regulator circuit easily designed with a smaller layout can be provided, and the semiconductor device can easily generate a given stable power source potential.

A double oven crystal oscillator (DOCXO) is disclosed which is highly stable by incorporating means to reduce the effects of ambient pressure changes on the frequency of the oscillator. The oscillator crystal is mounted in a temperature controlled inner oven to reduce the effects on the frequency stability of the oscillator. The oscillator circuitry and all circuitry associated with the inner oven is mounted in good thermal contact with the inner oven. A Faraday shield at ground potential is placed over the oscillator circuitry to minimize the effects of stray capacitance between the oscillator components and the case wall of the inner oven. The effects of minor deformations in the case walls within the oscillator caused by ambient pressure changes and other factors causing pressure changes are thereby greatly minimized. To further reduce effects on oscillator frequency stability the ovens of the DOCXO are temperature controlled, cases are hermetically sealed, the case walls are rigid, and ovens and cases may be evacuated.

A system and method for shallow water simulation may provide a framework for solving General Shallow Wave Equations (GSWE) to efficiently simulate 3D fluid effects on arbitrary surfaces using a height field representation. The height field representation may include height columns constructed along surface normals, which may be dependent on a condition of boundary cells adjacent to fluid cells and/or artificial viscosity effects. The framework may provide implicit schemes for solving for the effects of external forces applied to the fluid, including gravity and surface tension, and explicit schemes for solving for advection effects. The system and method may be implemented on general-purpose CPU(s) and/or GPU(s) and may be capable of simulating a variety of fluid effects including: waves, rivulets and streams, drops, and capillary events. In some embodiments, the system and method may achieve real-time fluid control and fluid shape design through user-interaction (e.g., in a graphical painting application).

A center panel that extends through the bottom, divides the receptacle into two compartments, and terminates in a handle proximate the open top. A footing on the center portion prevents the panel from being pulled through the receptacle. An open-topped tool tote has an open top, a center panel that divides the tote in a longitudinal direction, and a handle at the upper edge of the center panel.
