Title: Transmitting and receiving arrangement with at least two pairs of respectively one transmitting power amplifier and one low noise input amplifier
Inventor: BOPP MATTHIAS
IPC: H04B1/40
Filed: 2004-07-30
Abstract: A transmitting and receiving arrangement for operation in any selected one of plural frequency ranges includes at least one transmitting power amplifier and at least; one low noise input amplifier allocated respectively to each frequency range. The arrangement includes plural chips, that each include at least one input amplifier and at least one transmitting amplifier incorporated therein, e.g. in an integrated circuit. The input amplifier and the transmitting amplifier allocated to a particular frequency range are located on different chips. The input amplifier and the transmitting amplifier incorporated in one chip are allocated to different frequency ranges. In a communication in a given frequency range, the transmission amplification is handled through one chip and the input amplification is handled through a different chip. The dissipated heat from the transmitting amplifier does not directly heat and deteriorate the performance of the input amplifier allocated to the active frequency.

Title: Colostomy alert device and method
Inventor: ELLIOT NYLE
IPC: A61F5/445
Filed: 2004-09-08
Abstract: A method and apparatus for alerting a colostomate or medical attendant to the presence of fecal matter. The device includes a hollow plug detachably securable to a flexible port positioned about the stoma.

Patent CA-2490936-A1 (CA)
Inventor: TANG XIAO MING
IPC: G01V1/50
Filed: 2003-06-26
Abstract: The present invention is a method of determining formation horizontal shear wave velocity, formation transverse isotropy and an effective logging tool modulus. The method comprises determining an effective logging tool modulus by modeling the logging tool as a fluid filled cylindrical shell. Measured Stoneley-wave slowness values are acquired for a formation. A horizontal formation shear wave velocity, Vsh, is calculated as a function of the measured Stoneley-wave slowness and an estimated Stoneley-wave slowness wherein the estimated average Stoneley-wave slowness is computed using the effective tool modulus. A difference between the measured Stoneley-wave slowness and the estimated Stoneley-wave slowness is minimized and the horizontal shear-wave velocity value for the minimized difference is output.  Transverse isotropy may then be calculated as a function of the determined Vsh and vertical shear wave velocity, Vsh,determined from standard logging techniques.

Title: Profiled rail system for bridging floorcovering transitions
Inventor: SONDERMANN FRANK
IPC: E04F11/16
Filed: 2005-01-13
Abstract: A profiled rail system (1) is used for bridging floorcovering transitions, ends or staircase edges. The profiled rail system (1) has a base profile (2) and a covering profile (3). The base profile (2) has at least one vertical leg (6), on which an inner shell (9) of a rotary joint (10) is provided. This rotary joint (10) supports the covering profile (3) such that it can be pivoted. For this purpose, two webs (11) oriented downward are provided on the covering profile (3) and, in order to form an outer shell of the rotary joint (10), have at least two partly cylindrical inner contours (12) which lie one above another. These inner contours (12) are formed so as to match the inner shell (9) of the rotary joint (10). In this way, step by step adjustability of the covering profile (3) is implemented. The rotary joint (10) can be clicked as desired into respectively one of the partly cylindrical inner contours (12). In addition, the partly cylindrical inner contours (12) ensure pivotable mounting of the covering profile (3) with respect to the base profile (2).

Abstract: A powered tool (20) for performing surgical procedures. The tool (20) includes a handpiece (22) in which a power generating unit (26) is housed. A control member is mounted to the handpiece (22). The control member (38) is mounted to the handpiece (22) so that the orientation of the control member (38) can be selectively set relative to the point to which it is mounted to the handpiece (22) and so it can move relative to a reference point on the handpiece. A  control module (36) monitors the orientation of the control member (38) and its position relative to the reference point. Based on the control member (38) orientation and position, the control module (36) generates signals to regulate the operation of the power generating unit (26). When the power generating unit (26) is a motor, the control module generates signals to ensure that the maximum speed at which the motor can be driven is less than the no load speed.

Title: Determination of leak and respiratory airflow
Inventor: BERTHON-JONES MICHAEL
IPC: G01M3/26
Filed: 1997-08-14
Abstract: Methods and apparatus for determining leak and respiratory airflow are disclosed. A pressure sensor (34) and a differential pressure sensor (32) have connection with a pneumotach (24) to derive instantaneous mask pressure and airflow respectively. A microcontroller (38) estimates a non-linear conductance of any leak path occurring at a mask (12) as being the low pass filtered instantaneous airflow divided by the low pass filtered square root of the instantaneous pressure. The instantaneous leak flow is then the conductance multiplied by the square root of the instantaneous pressure, and the respiratory airflow is calculated as being the instantaneous airflow minus the instantaneous leak flow. The time constants for the low pass filtering performed by the microcontroller (38) can be dynamically adjusted dependent upon sudden changes in the instantaneous leak flow.
