Abstract: Systems and methods for verifying compliance of a communication device with one or more requirement specifications is provided. In one exemplary embodiment, a method may be performed at a communication device for verifying compliance of the communication device with a requirement specification. Further, while a test loop is activated in the communication device, the method may include receiving, at a receiver of the communication device and on a downlink of a radio link, downlink data. In response to determining an occurrence of an event specific to verifying the compliance of the communication device with the requirement specification and used to control when the communication device transfers the received downlink data from the receiver to a transmitter of the communication device, the method may include transferring, from the receiver, to the transmitter, the received downlink data. Also, the method may include transmitting, from the transmitter on an uplink of the radio link, the received downlink data.

Abstract: A method and apparatus for testing point-to-multipoint services and other wireless communication services dependent on unidirectional radio bearers and/or unacknowledged mode operations is described herein. A wireless communication device activates a test module responsive to receiving a test activation message. During a test mode, the test module receives RLC data units from a test system via a unidirectional downlink radio bearer or a control channel. In one embodiment, the test module includes a metric evaluator that determines an error metric based on the received RLC data units. The test module reports the error metric to the test system. In another embodiment, the test module includes a loop-back module that loops-back at least a portion of the received RLC data units to the test system via a unidirectional uplink radio bearer.

Abstract: A method for verifying compliance of a communication device with one or more requirement specifications is disclosed. The method comprises establishing a link between a test system and the communication device, wherein the establishing comprises configuring one or more bearers and one or more control channels; closing a test loop comprising the test system and the communication device, wherein the closing comprises activating a test loop function of the communication device; sending data in a downlink of the test loop from the test system to the communication device; receiving the data at the communication device; transferring at least some of the data to an uplink transmission arrangement of the communication device after a specific event has occurred; and verifying, at the test system, transmission in an uplink of the test loop from the communication device to the test system. Corresponding test system and test loop function arrangement are also disclosed.

Abstract: Methods for measuring the flow differential through a dialysis machine are disclosed in which the dialysis machine includes a heat exchanger having a primary side and a secondary side for exchanging heat therebetween. The method includes measuring the temperature differences across the primary and secondary sides of the heat exchanger and calculating the flow differential based upon these measured temperature differences. Apparatus for measuring such a flow differential is also disclosed, as are methods for calibrating that apparatus.

Abstract: Apparatus for monitoring flow of a dialysis fluid through a dialyzer is disclosed including a computer for calculating the flow rate of the dialysis fluid into and out of the dialyzer based on the formula P-P.sub.O =k*Q.sup.n in which P is the pressure in the dialysis fluid between a throttle and a pump either upstream or downstream of the dialyzer, P.sub.O is the pressure in the dialysis fluid on the opposite side of the throttles from the pump, k is a characteristic coefficient for the throttle, Q is the flow of the dialysis fluid through the throttle, and N is a characteristic exponent for the throttle, and the apparatus includes microprocessor for calculating the values of k and P.sub.O prior to use and for calculating the value of P.sub.O during use of the dialyzer. Methods for carrying out such monitoring are also disclosed.
