| 20090299273 | REMOTE EXCHANGE PERITONEAL DIALYSIS - A portable, flexible peritoneal dialysis system is disclosed. The system includes a flexible harness, such as canvas or cloth, to mount a stiff housing with a heater for holding and heating fresh dialysis fluid. The harness includes straps or other suspending devices for holding a second, flexible housing for a drain bag for holding sent dialysis fluid. The upper portion of the system includes a hook and a load cell for suspending the remaining portions. The load cell is used to measure the weight of the apparatus. By keeping track of the weight and the changes, the quantity of fluid removed from the patient, spent dialysate, is tracked, as is fresh dialysate infused into the patient. An electronics or control portion controls heating of the fresh dialysate, and operation of pumps and valves for moving the dialysate. This portion also includes alarms and communications equipment. | 12-03-2009 |
| 20100130918 | SYSTEMS AND METHODS FOR REMOVING AIR FROM SUPPLY CONTAINERS AND ASSOCIATED FILL TUBING - In one embodiment, a patient connection system for peritoneal dialysis includes: a housing; a fill container occluder valve carried by the housing; a drain container occluder valve carried by the housing; a shunt connector positioned at the housing, so as to be removeably connected into a fill container line and a drain container line to allow fresh dialysis fluid to run from the fill container to prime the fill container line when the fill and drain container occluder valves are open; and a patient transfer set support provided by the housing, the patient transfer set support configured to allow a patient transfer set to be connected to the fill container line after the fill and drain container occluder valves have been closed and the shunt connector has been disconnected from the fill and drain container lines. | 05-27-2010 |
| 20100130919 | SYSTEMS AND METHODS FOR REMOVING AIR FROM THE PATIENT'S PERITONEAL CAVITY - A peritoneal dialysis (“PD”) connection apparatus includes a first connector for connecting to a PD fluid fill line; a second connector in fluid communication with the first connector, the second connector including a filter configured to allow air but not fluid to pass through the filter; and an air-tight cap manually removeable and resealable to the second connector so as to selectively expose the filter to allow air trapped in a patient's peritoneum to be vented to atmosphere. | 05-27-2010 |
| 20110093294 | PERITONEAL DIALYSIS OPTIMIZED USING A PATIENT HAND-HELD SCANNING DEVICE - A dialysis system includes: a portable device configured to be carried by a patient and to read a marking displayed on a dialysis fluid container, the device obtaining data concerning at least one of a dialysis fluid type and a dialysis fluid volume from the marking; the device defined dialysate dwell time, alert patients for the next exchange and further configured to transfer the data to a computer; and wherein the computer is configured to use the data to track therapy progress of the product. | 04-21-2011 |

| 20090185510 | RF PROCESSOR HAVING INTERNAL CALIBRATION MODE - The present invention pertains to a method of calibrating reception properties of a radio frequency (RF) processor. The application describes two embodiments of the invention representing calibration of the properties using an auxiliary transmitter to generate a calibration signal internal to the RF processor. | 07-23-2009 |
| 20090186582 | SYSTEM AND METHOD FOR TRANSMISSION INTERFERENCE CANCELLATION IN FULL DUPLEX TRANSCEIVER - A full duplex transceiver has cancellation circuitry that includes an auxiliary receiver and an auxiliary transmitter. More specifically, an analog received signal that includes transmission signal leakage is provided to a low noise amplifier (LNA), which then provides its output to a main receiver and the auxiliary receiver. The auxiliary receiver includes a portion operable to convert the received signal from the analog domain to the digital domain. The auxiliary receiver additionally includes a cancellation processor that determines the transmission signal leakage and generates a signal based on the determined leakage. This signal generated by the auxiliary receiver is provided to the auxiliary transmitter, which converts the digital signal back to the analog domain and generates a cancellation signal. The analog cancellation signal is fed back and added to the received signal at the input of the LNA. As a result of the feedback system including an auxiliary receiver and an auxiliary transmitter, transmission signal leakage of many types may be canceled from a received signal. | 07-23-2009 |
| 20100165895 | METHODS AND APPARATUS FOR CANCELING DISTORTION IN FULL-DUPLEX TRANSCEIVERS - Methods and apparatus for canceling distortion in full-duplex transceivers are disclosed. Some example methods to reduce distortion in a full-duplex transceiver include generating a first digital signal, generating a first analog signal based on the first digital signal for transmission over a full-duplex channel, receiving a second analog signal via the full-duplex channel, and generating a second digital signal based on the second analog signal, wherein the second digital signal includes coupling distortion based on the first analog signal. The example methods further include generating an adaptive filter signal based on the first digital signal, and reducing the coupling distortion from the second digital signal by subtracting the adaptive filter signal from the second digital signal. | 07-01-2010 |
| 20100330942 | LINEARITY OF AN RF RECEIVE PATH BY SPURIOUS TONE SUPPRESSION - A method of increasing linearity of an RF signal receive path includes measuring a signal amplified by the receive path. The receive path has a local oscillator operating at an LO frequency and a ground. An error signal is determined from the amplified signal, the error signal being representative of the nonlinearity. An anti-spur tone is injected into the ground. The anti-spur tone has a frequency about equal to the LO frequency and an amplitude and phase that are determined to increase the linearity of the receive path. | 12-30-2010 |
