Title: Motor vehicle speed control system
Inventor: RICHARDSON MICHAEL JULIAN
IPC: G01S13/931
Filed: 2000-09-22
Abstract: A motor vehicle speed control system 4, comprises an adaptive cruise control system 6, an own vehicle speed and path determination system 8, a radar unit 10, and means for determining the angular offset 16 of one or more preceding vehicles 20 with respect to the own vehicle 2. The radar unit has at least one radar transmitter 12 and at least one radar receiver 14. The speed and path determination system 8 is capable of measuring and predicting the speed 3 and path 7 of the own motor vehicle 2, calculating the relative position and relative speed of the own motor vehicle 2 with respect to said one or more of the preceding vehicles 20, and determining the extent 18 to which a preceding motor vehicle 20 is in the path 7 of the own motor vehicle 20. The adaptive cruise control system 6 controls the own vehicle speed 3 to control a minimum distance or time headway 22 between the own vehicle 2 and an immediately preceding vehicle 20 in the path 7 of the own vehicle 2. When the immediately preceding vehicle 20 is detected to move out of the path 7 of the own vehicle 2, the headway between the vehicles is progressively reduced.

Title: Tracheostomy assembly
Inventor: NASH JOHN EDWARD
IPC: A61M16/04
Filed: 2000-10-11
Abstract: An obturator 2, for a tracheostomy tube 1 has a handle 25, and an enlarged, hollow patient end (21), divided between a tapering forward section 22, and a rear section 23, having a constant, oval cross section. The obturator 2 is inserted in the tracheostomy tube 1 so that the tapering section 22 is located forwardly of the patient end 11 and the oval section 23, extends through the patient end of the tube. The oval shape of the obturator 2 provides a smooth transition between the obturator and the patient end 11 of the tube 1 because the patient end of the tube is distorted to an oval shape when it is straightened by insertion of an obturator.

IPC: B01F15/04
Filed: 2000-05-08
Abstract: A static mixer comprising a group of deflector elements distributed within a conduit through which a fluid flows in a direction generally parallel to an axis of the conduit. Each deflector element defines a surface which is inclined to the conduit axis such that the fluid is deflected by the surface in a direction transverse to that axis. The deflector elements are positioned so as to generate an asymmetric vortex flow such that the intensities of adjacent vortices are different.

Title: Method and data processing system for software testing of a device driver
Inventor: TRAN THOMAS HUNG
IPC: G06F11/36
Filed: 2001-03-05
Abstract: A system and method are disclosed for testing a device driver on a data processing system. An operating system allocates a memory address range for executing a device driver. The device driver is executed as an application on top of the operating system to test the device driver. The system and method monitor to detect whether a target address for a request made by the device driver is within the memory address range.

IPC: H04M1/72436
Filed: 2002-01-04
Abstract: A method of transmitting and receiving e-mail messages which allows increased personal expression of the sender to be seen or heard by the recipient. In a transmitting portable communication terminal 1, characters are inputted 2 (a-1) to form character data for an e-mail message. Additional expression data in inputted 3 (a-2), the additional expression data giving a variation on the respective characters of the character data. In one embodiment, the additional expression data relates to a character size, character colour or character font in which the e-mail characters are to be displayed. In another embodiment the additional expression data is voice characterizing data which adds tone, accent, stress or intonation to the characters of the e-mail message for when it is reproduced using a voice generator at the receiver terminal. In this embodiment the additional expression data may be input by the sender using a microphone 3. Transmission data 4 is generated by linking and converting the character data with the additional expression data. The transmission data is transmitted as e-mail (a-4) to the recipient. In a receiving portable terminal 6 the transmission data is received (b-1). The character data and additional expression data are then regenerated 8 (b-2) from the transmission data. The characters of the character data are then displayed on a screen 9 according to the additional expression data according to the desire of the sender. In another embodiment the receiver terminal reproduces the e-mail character audibly using a voice generator 11 applying the additional voice expression data.

Title: An attenuation arrangement with a series connection of an FET and an inductance in parallel with a capacitance
Inventor: SASABATA AKIHIRO
IPC: H03H11/24
Filed: 2002-04-08
Abstract: A resonance type SPST switch is formed by connecting an inductive element in series with the drain of an FET, and then by connecting a capacitive element in parallel with the series connection of the FET and the inductive element. A constant-voltage source for feeding a voltage Vs is connected to the source of the FET, and a variable-voltage generator for switching the FET between an on state and a state in the vicinity of pinchoff is connected to the gate of the FET. When the variable-voltage generator feeds a voltage V  a   in the vicinity of a pinchoff voltage to the gate of the FET, the SPST switch is closed while the amount of attenuation between first and second terminals is variably set. The resulting variable attenuator is thus compact in size, allows a large amount of attenuation to be set, and involves low manufacturing costs. Various other attenuator/switches using the basic series/parallel arrangement are disclosed.

Abstract: A vibratory mechanism 26 for a compactor (Fig 1) with a vibrating drum (14,16) comprises a first eccentric weight 50 on a shaft 54, 58, 72, a second eccentric weight 52 on a shaft 56, 60, 76 and a clutch 70 interconnecting the shafts and allowing relative rotation of the weights to vary the vibration amplitude of the mechanism. The inner weight 50 is directly driven from motor 28 via inner shaft 54, inner drive shaft 58 and shaft 72. The outer weight 52 is supported on a stub shaft 56 and driven along with the inner weight via an outer drive shaft 60, a shaft 76 and a clutch 70 with a clutch pack 78. The clutch 70 may be an electric, hydraulic or spring-actuated disc clutch. As the motor 28 is brought up to speed, the clutch 70 is activated momentarily to allow the shafts 72, 76 to slip relative to each other until the weights 50, 52 are positioned 180 deg out of phase giving a vibration amplitude of zero. The clutch is then re-engaged and the shafts 72, 76 brought up to speed. The clutch is then activated again to allow the weights to move towards each other to increase the vibration amplitude to a desired level. The clutch activation is automatically controlled (controller 100, Fig 4).
