Title: Frequency translation apparatus and method
Inventor: LAROSA CHRISTOPHER P
IPC: A61F13/15
Filed: 1992-09-21
Granted: 1998-08-11
Abstract: The present invention discusses a frequency translation apparatus for altering the effective frequency of the phase information of an input signal (115). The input signal (115) has a first phase (~(t)) and a first frequency (fi). The phase of the input signal is extracted and digitized at a second frequency (fO), forming a second N-bit digital phase signal (~'(t))(311). The frequency translation apparatus generates a third digital phase signal (319) which approximates the difference between ~(t) and ~'(t). Then, the frequency translation apparatus (313) combines the second digital phase signal and the third digital phase signal, forming a fourth digital phase signal (307) substantially approximating the first phase signal.

Patent CA-2116134-C (CA)
Inventor: SHARP GORDON P
IPC: B08B15/02
Filed: 1992-08-17
Granted: 1999-10-05
Abstract: This invention relates to a fume hood controlling method and apparatus which reduces the amount of replacement air required to operate a fume hood (10) by permitting the fume hood to operate at a relatively low face velocity in the absence of a containment affecting condition, but which is capable of detecting the occurrence of a containment affecting condition, such as the presence or movement (34) of a user within a selected area of the face of the fume hood, and of increasing face velocity to a selected level in response to such detection. When the detected condition no longer exists, the control automatically returns the fume hood to the lower face velocity, preferably with a time delay. Maximum replacement air volume and minimum replacement air volume may also be controlled in response to such detection.

Abstract: The apparatus for clamping a work piece at a work station of a machining apparatus in a well defined position comprises a base member to be fixed in the working area of a machining apparatus and a work piece carrier member adapted to be put onto the base member and to be fixed thereto. The base member and the work piece carrier member each comprise pair wisely cooperating aligning means in order to align the position of the work piece carrier member with respect to the base member along three coordinate axes running perpendicularly to each other as well as with regard to the angular position. Clamping means adapted to develop a clamping force to fix the work piece carrier member to the base member in the well defined position which is defined by the aligning means are provided. The aligning means comprise first aligning element pairs for the definition of the position of the work piece carrier member in the Z-axis in the form of cooperating reference surfaces located at the work piece carrier member and the base member, re-spectively, and the aligning means further comprise second align-ing element pairs for the definition of the position of the work piece carrier member in the X-axis and third aligning element pairs for the definition of the position of the work piece carrier member in the Y-axis. Both the second and third aligning element pairs are in the form of cooperating linear aligning element pairs. The cooperating linear alignment pairs each comprise a wedge-shaped centering ruler member and a counterpart member with a matching centering slit. The clamping means comprises a plural-ity of clamping members, each including a clamping pin member fixed to the work piece carrier member and a clamping chuck member located in the base member. The work piece carrier member com-prises an essentially even, continuous flat surface at its side which faces the base member if the work piece carrier member is clamped to the base member, the flat surface portionally forming one of the reference surfaces. Each one member of the second and third linear aligning element pairs for the definition of the po-sition of the work piece carrier member in X- and Y-direction is directly connected to the flat surface, and each of the clamping pin members of the clamping means is also directly connected to the flat surface.

Abstract: A header is mounted on a separate tractor and takes drive from a PTO shaft of the tractor and communicates the drive to a main drive shaft of the header longitudinal of the main beam of the header. The angle drive necessary to communicate this power is formed by three CV joints. A first CV joint is connected to the PTO shaft and a third CV joint is connected to the main drive shaft of the header. Between the first and third CV joints is provided a first shaft extending to the second CV joint and a second shaft from the second CV joint to the third CV joint. The first shaft is carried on a hanger bearing which can pivot about a horizontal axis with the first shaft mounted in a spherical bearing on the hanger bearing plate. The second shaft is telescopic. The three CV joints pivot to divide the total angle approximately equally so that each can run within a reasonable angle. The pivoting hanger bearing and the telescopic shaft accommodate relative movement between the tractor and the header.

Title: Multiple access cellular communication with circuler interleaving and reduced dropped-packet runlengths
Inventor: PAPADOPOULOS HARALABOS C
IPC: H04W74/04
Filed: 1995-11-15
Granted: 1999-10-05
Abstract: An apparatus and method for reducing the runlength of dropped packets in multiple access cellular communication systems.  The invention is particularly well suited for use in time-division multiple access (TDMA) systems such as, for example, shared time-division duplexing (STDD) systems, and TDMA/TDD  systems with  speech activity detection  (SAD). Frame time or frequency slots for communicating information are allocated to a first set of active users.  A second set of active users which are not allocated a slot in a given frame are identified.   At least one of the users in the second set which remains active in a subsequent frame is provided with a priority in obtaining an allocated slot in the  subsequent  frame.    In  one  embodiment,  the  slots allocated to particular active users in the given frame are shifted by at least one slot position if the same users are allocated slots in the subsequent frame.   The priority allocation and slot position shifting may be implemented by circular interleaving of the first set of users which have been allocated slots in the given frame with the second set of users which remain active but were not allocated slots in the given frame.  The circular interleaving may be utilized with fast speech activity detection  (FSAD)  in order to further reduce dropped-packet runlengths.
