    • A rotary device is described for use in a rotary engine, or a compressor, or turbine, the rotary device comprising two rotors disposed adjacent each other and rotatable about substantially parallel axes of rotation. Each of the rotors has protrusions extending therefrom at regular intervals about the circumference of each to define an open portion of a sealable compression chamber between adjacent protrusions. Each protrusion has two side surfaces and a projecting end surface, wherein the meeting point between each side surface and the projecting end surface defines a tip. The two rotors are arranged such that upon contra rotation of the rotors, a protrusion of one of the rotors engages between a pair of protrusions on the other rotor, and the tips of the engaging rotor are in constant sealing contact with the opposing side surfaces of the pair of protrusions for a predetermined period of time. During the predetermined period of time, a sealed chamber is formed and the volume of the chamber is reduced to a predetermined level by the contra rotation.

    • TOF system shutter time needed to acquire image data in a time-of-flight (TOF) system that acquires consecutive images is reduced, thus decreasing the time in which relative motion can occur. In one embodiment, pixel detectors are clocked with multi-phase signals and integration of the four signals occurs simultaneously to yield four phase measurements from four pixel detectors within a single shutter time unit. In another embodiment, phase measurement time is reduced by a factor (1/k) by providing super pixels whose collection region is increased by a factor “k” relative to a normal pixel detector. Each super pixel is coupled to k storage units and four-phase sequential signals. Alternatively, each pixel detector can have k collector regions, k storage units, and share common clock circuitry that generates four-phase signals. Various embodiments can reduce the mal-effects of clock signal transients upon signals, and can be dynamically reconfigured as required.
    • 在获取连续图像的飞行时间(TOF)系统中获取图像数据所需的TOF系统快门时间减少,从而减少相对运动发生的时间。 在一个实施例中,通过多相信号对像素检测器进行时钟控制,并且四个信号的积分同时发生,以在单个快门时间单位内从四个像素检测器产生四相测量。 在另一个实施例中,通过提供相对于正常像素检测器的收集区域增加因子“k”的超像素,将相位测量时间减小因子(1 / k)。 每个超像素耦合到k个存储单元和四个相序的信号。 或者,每个像素检测器可以具有k个集电极区域,k个存储单元,以及共享产生四相信号的公共时钟电路。 各种实施例可以减少对信号的时钟信号瞬变的不良影响,并且可以根据需要动态地重新配置。

    • An improved implantable valve accumulator pump for the delivery of medication is disclosed. The implantable pump comprises a pressurized drug reservoir. The medication metering assembly comprises a fixed volume accumulator positioned between a pair of valves. The valves alternately open and close to admit medication from the reservoir into the accumulator and to dispense a precise volume pulse to an outlet catheter. In order to improve the pump's accuracy and to increase pumping volume while optimizing the pump's overall size and energy usage a two way diaphragm accumulator is used. The unit can be externally programmed or can be used in a fixed rate configuration that is never programmed but set at the factory or in the current programmable configuration.

    • An intramedullary nail has a proximal part for engagement with a proximal bone fragment and a distal part for engagement with a distal bone fragment. A motion assembly interconnects the parts and allows limited axial relative motion of the proximal and distal parts. This limited axial motion provides micromotion and in some embodiments also dynamisation. The nail may comprise a stem for fastening to one bone fragment and an insert within the stem for fastening to the other bone fragment, the insert being adapted to guide insertion of a bone screw through the stem and to prevent relative rotation of the distal and proximal bone fragments. The motion assembly may include spring bias and/or damping means between the parts, possibly including one or more Belleville washers.
