    Abstract: A video circuit including a video amplifier adapted to generate an amplified output video signal from an input video signal; a short detection circuit adapted to generate a first signal indicative of whether there is a short present at an output of the video amplifier; and a load detection circuit adapted to generate a second signal indicative of whether there is a load coupled to the output of the video amplifier. The video circuit may further include an input signal detection circuit adapted to generate a third signal indicative of whether an input video signal is present. The third signal generated by the input signal detection circuit may be used to enable the outputting of the first and second signals in order to prevent the false indication of faults at the output of the video amplifier in the absence of an input video signal.

    Abstract: In a golf bag that includes a body with a top end and a bottom end, a throat structure is mounted in the top end of the body. The throat structure has a substantially ring shaped outer wall and a raised inner wall extending transversely of the body top end with its opposite ends connected to the outer wall. A first plurality of three divider walls extends between the inner and outer walls to define a first plurality of four individual compartments located along a back portion of the throat structure. Each compartment of the first plurality of individual compartments is adapted for receiving one wood-type golf club. A raised well is located along a front portion of the throat structure opposite the first plurality of individual compartments. The raised well is adapted for receiving a golf putter. A second plurality of two divider walls extends between the raised inner wall and the raised well to define a second plurality of three individual compartments located between the front and back portions of the throat structure. Each compartment of the second plurality of individual compartments is adapted for receiving a plurality of iron-type golf clubs.

    Abstract: Methods and systems are provided for adapting signals from an ultrasound transducer for an ultrasound system. Where the signal processing in a transducer assembly outputs data incompatible with the ultrasound system, circuitry provided within the transducer assembly converts the data to be compatible with the ultrasound systems. For example, sub-array mixing is provided to partially beamform signals from a plurality of transducer elements. The resulting output signals from a plurality sub-arrays are provided through a cable to a connector housing of the transducer probe assembly. Since the mixers alter the data, such as shifting the data to an intermediate frequency, the output data may be at a frequency different than the frequencies for operation of the receive beamformer. Additional mixers are then provided to convert the intermediate frequency signals to radio frequency signals that may be processed by the ultrasound systems received beamformer. As another example, signals from a plurality of transducer elements are multiplexed together. Where the receive beamformer is not operable to de-multiplex such signals, circuitry within the transducer probe assembly converts the signals by de-multiplexing the data for beamforming. Ultrasound systems have a limited number of received beamformer channels. By providing signal processing, conversion, and/or partial beamforming within the transducer probe assembly, the number of elements used may be different than the number of received beamformer channels provided by the system.

    Abstract translation: 提供了用于适应来自用于超声系统的超声换能器的信号的方法和系统。 在传感器组件中的信号处理输出与超声系统不兼容的数据的情况下，提供在换能器组件内的电路将数据转换为与超声系统兼容。 例如，提供子阵列混合以部分地波束来自多个换能器元件的信号。 来自多个子阵列的所得到的输出信号通过电缆提供到换能器探头组件的连接器壳体。 由于混频器将数据改变为中频，所以输出数据可能处于与接收波束形成器的操作频率不同的频率。 然后提供额外的混频器以将中频信号转换成可由超声系统接收波束形成器处理的射频信号。 作为另一示例，来自多个换能器元件的信号被多路复用在一起。 在接收波束形成器不可操作以解复用这种信号的地方，换能器探头组件内的电路通过对波束成形的数据进行解复用来转换信号。 超声系统具有有限数量的接收波束形成器通道。 通过在换能器探头组件内提供信号处理，转换和/或部分波束成形，所使用的元件的数量可以不同于由系统提供的接收波束形成器通道的数量。

    Abstract: A cutter drive for a computer driven printer/plotter employs a cutter carriage which is separate from the printer carriage and which is attachable to and detachable from the printer carriage to be moved thereby without a separate cutter drive. Camming surfaces on a pickup arm and a pickup hook permit the cutter carriage to be mechanically engaged and disengaged from the printer carriage without any motors or magnets.

    Abstract: The present invention includes tools, tool kits and methods useful for treating an SI joint. In one embodiment, the present invention is a method including the steps of: implanting a graft into a SI joint of a patient, wherein the implanting comprises: creating an incision in the patient's skin proximal to the patient's SI joint; dilating the incision; creating a void in the SI joint, wherein the creating comprises displacing a portion of the patient's ilium and a portion of the patient's sacrum; and inserting a graft into the void in the SI joint, wherein the graft contacts the patient's iluim and the patient's sacrum and wherein the graft is configured to substantially fuse the patient's ilium to the patient's sacrum, thereby substantially immobilizing the patient's SI joint; inserting and immobilizing screw perpendicular to and through the inserts within the void created in the sacroiliac joint.
