Abstract: A work implement includes a support controller disposed in communication with a hydraulic lift cylinder. The support controller initiates a control activation signal for commanding movement of the hydraulic lift cylinder to move the head support from an initial start position to a commanded support position. The support controller determines a stop signal position based on the current rate of movement of the head support toward the commanded support position. The stop signal position may further be based on a current fluid pressure of an associated float system. The support controller ceases or stops the control activation signal when the head support reaches the stop signal position, whereby the head support decelerates over a distance after cessation of the control activation signal such that the head support substantially stops movement at the commanded support position.

Abstract: The embodiments of the present invention are directed to a novel wireless powered method, apparatus and tracking system without a wired interface to a moving catheter. The implant in the patient's body on the moving catheter is energized by an external ultrasound transmitter using acoustic pressure waves. As a general mode of operation, ultrasonic waves from outside of a patient's body are received by an array of transducer elements configured about the catheter disposed in a patient's body, wherein the array of transducer elements transforms a frequency into a resultant stored energy. The resultant stored energy powers one or more transceivers via a power management arrangement and enables RF frequencies in a desired band to be output and received by external sensors. Coupled with ultrasound backscattering capabilities, the catheter provides a dual mode for accurate triangulated locations of the distal end of a moving catheter.

Abstract: An N-element baseband (BB) time-domain spatial signal processor system and methodology for large modulated bandwidth multi-antenna receivers are provided. Such a processor generally includes a pipeline converter configured as an asynchronous time-to-digital converter, wherein the asynchronous time-to-digital converter arrangement generates a residue value and an asynchronous pulse and is further arranged to amplify the residue value so as to result in an amplified residue value; and a 2-bit flash time-to-digital-converter configured to quantize the amplified residue value. Thus, a true-time delay spatial signal processing system and technique in the time-domain that enables beamforming, beam-nulling and multiple independent interference cancellation after time-alignment of signals using cascaded voltage-to-time converters and quantization using relaxed pipeline time-to-digital converters is presented.

Abstract: A discrete-time delay (TD) technique in a baseband receiver array is disclosed for canceling wide modulated bandwidth spatial interference and reducing the Analog-to-Digital Conversion (ADC) dynamic range requirements. In particular, the discrete-time delay (TD) technique first aligns the interference using non-uniform sampled phases followed by uniform cancellation using a cancellation matrix, such as, for example, a Truncated Hadamard Transform implemented with antipodal binary coefficients.

Abstract: Unique methods and bio-imaging systems are introduced herein for self-automated self-operable biomedical devices and methods for bio-signal monitoring, such as electrocardiograms (ECG), heart rate, and other vital signs, requiring no trained medical assistance or minimal assistance. In particular, methods and devices disclosed herein may require no dedicated medical resources, generate diagnostic quality results, and provide for motion artifact correction without inducing discomfort or irritation. Moreover, long term recording is realizable. Such methods and devices reduce the backlog of patients at out-patient wards as well as emergency response in remote areas.

Abstract: A patient fluid absorption and estimation device includes an absorbent layer comprising an absorbent material and adapted to absorb fluids. The device's sensing layer includes piezoresistive element(s). The sensing layer abuts the absorbent layer such that changes in at the mass or shape of the absorbent layer cause a change in the strain in the piezoresistive element(s). The device includes memory and processing in communication with the memory. The processing includes a piezoresistive element interface. The processing senses a voltage, representing an estimation of the amount of fluid absorbed, across each element via the interface. The processing then converts each voltage to a digital value, and stores the value in the memory. The device includes wireless communications that receives commands from an external computer system to transmit the values, and transmits the values to the external. A power subsystem powers each subsystem.
