Title: Power saving in cache memory by skipping access to same cache line
Inventor: CHOI HOON
IPC: G06F12/08
Filed: 2001-02-23
Abstract: A digital data processing system is provided which includes a digital data processor, a cache memory having a tag RAM and a data RAM, and a controller for controlling accesses to the cache memory. The controller stores state information on access type, operation mode and cache hit/miss associated with the most recent access to the tag RAM, and controls a current access to the tag RAM just after the preceding access based on the state information and a portion of a set field of a main memory address for the second access. The controller determines whether the current access is applied to the same cache line that was accessed in the first access based on the state information and a portion of a set field of the main memory address for the second access, and allows the current access to be skipped when the current access is applied to the same cache line that was accessed in the preceding access.

Title: Methods to improve electrostatic particle measurement
Inventor: REAVELL KINGSLEY STJOHN
IPC: G01N15/02
Filed: 2001-04-18
Abstract: An electrostatic instrument for measuring particle concentrations and possibly sizes in aerosols, such as an Electrostatic Low Pressure Impactor or Differential Mobility Analyser suffers from errors which limit the useful response bandwidth of the device. The invention minimises or eliminates these transient errors which are caused by changing particle concentrations in the aerosol. A system may be added to an otherwise conventional instrument to compensate for the transient effects based on a model of the charge production mechanism. Alternatively, a screening electrode 8 placed over the sense electrodes 7 in the instrument, and held at a controlled electrical potential difference, is added to the instrument to eliminate the effect. A third embodiment adds compensating electrodes which provide a direct measurement of the transient effect which can be subtracted from the signal.

Title: Rotatable mixer for sample recovery
Inventor: MARPLE VIRGIL A
IPC: B01F29/62
Filed: 2001-12-05
Abstract: Cascade impactors are used for testing the size distribution of particles emitted by pharmaceutical inhalers. The inlet used to introduce the particles into the cascade impactors are called USP (United States Pharmacopeia) induction ports. Particulate matter needs to be removed from the inside of these ports after each test by means of a solvent which dissolves the active drug material. The solvent is mixed with the particulates in mixer 12 which supports cradle 24 on which USP induction port 50 is attached by means of screws 32A, 32B and cup members 36A, 36B. The cup members 36A, 36B serve to cover the open ends 42A and 44A of the induction port 50. The cradle is then rotatably driven by means of motor 46 which drives shaft 22A and the motor may be controlled by computer 48. Pre-separators (Fig 4, 60) , which are used for removing large diluent particles prior to the induction port, may also be mixed and cleaned in a similar manner.

Title: Mobile terminal device having a position information detection function.
Inventor: YUGAMI KAZUYUKI
IPC: H04L29/08
Filed: 2002-07-24
Abstract: A mobile terminal device has a function for receiving and transmitting an e-mail message implemented in a control unit 12. The current position of the mobile terminal device is sensed by a GPS unit 16, and is output periodically, initiated by a timer 15, transmitting via a radio unit 11 the position information of the mobile phone in an e-mail to an address stored in a memory 13. The control unit may control the transmissions such that a transmission only takes place if the current position information differs from the previously transmitted position information. The position information is thus transmitted without user intervention, without the need for the base station to call the mobile terminal device, and without special equipment at the base station or network switch.

Title: Resilient packer set at a pressure threshold
Inventor: VAYNSHTEYN VLADIMIR
IPC: E21B23/04
Filed: 2000-04-20
Abstract: A packer 80 for use inside a casing (70, figure 4) of a subterranean well includes a resilient element 84, a housing 104 and a rupture disc 124. The resilient element is adapted to seal off the well annulus when compressed by the housing in response to pressure exerted by the annulus fluid on a piston head 119 of the housing. The housing includes a port 122 for establishing fluid communication with the annulus. The rupture disc prevents the fluid in the annulus from entering the port and contacting the piston head until the pressure exerted by the fluid exceeds a predetermined threshold and ruptures the disc. The packer may include a swab cup (figure 14) that allows the annulus above the packer to be pressurised. Once the packer is set, then in some embodiments the tubing can be moved with respect to the packer.

Title: MIMO system with H-ARQ and modification of channel response for retransmitted packets
Inventor: MCNAMARA DARREN PHILLIP
IPC: H04B1/707
Filed: 2004-02-27
Abstract: In a communication system employing plural transmit and receive antennas, a packet is retransmitted if it is not received correctly in response to a negative acknowledgment (NACK) from the receiver. For the retransmitted packet the channel response is made different to thatb for the original packet. This is done by one or more of : selecting a different subset of transmit and/or receive antennas for the communication, altering the polarisation or resonant modes of selected antennas, use of a scattering device around the antennas, or use of a channel scrambler at the transmitter. In MIMO-OFCDM systems, spreading in the time domain and not in the frequency domain can be performed. The difference between the original and retransmission channel response should preferably be made as large as possible.
