Patent BR-9913544-A (BR)
Inventor: TASSOUDJ ALI MOHAMMAD
IPC: H01Q5/00
Filed: 1999-09-07
Abstract: A dielectric resonator antenna (100) having a resonator (104) formed from a dielectric material mounted on a ground plane (108). The ground plane (108) is formed from a conductive material. First and second probes (112, 116) are electrically coupled to the resonator (104) for providing first and second signals, respectively, to or receiving from the resonator (104). The first and second probes (112, 166) are spaced apart from each other. The first and second probes (112, 116) are formed of conductive strips that are electrically connected to the perimeter of the resonator (104) and are substantially orthogonal with respect to the ground plane (108). The first and second signals have equal amplitude, but 90 degrees phase difference with respect to each other, to produce a circularly polarised radiation pattern. A dual band antenna (200, 220) can be constructed by positioning and connecting two dielectric resonator antennas (204, 208; 224, 228) together. Each resonator (204, 208; 224, 228) in the dual band configuration (200, 220) resonates at a particular frequency, thereby providing dual band operation. The resonators (204, 208; 224, 228) can be positioned either side by side or vertically relative to each other.

Patent GB-2354693-A (GB)
Title: Vermin trap
Inventor: PEARCE GRAHAME KENNETH
IPC: A01M23/38
Filed: 2000-08-25
Abstract: A vermin trap 1 comprises two terminals, an electrical floor plate 14 and an electrical shelf 16. A rodent can only enter the trap 1 through an access hole 12. Once inside the trap 1 the rodent goes around a barrier 18 and steps on the floor plate 14. In order to reach some bait inside a tube 20 the rodent has to reach up to the shelf 16. On touching the shelf 16 the rodent completes an electrical circuit and a current passes through the rodent. This current is sufficient to kill the rodent. The trap may be tubular and comprise two entrances and three terminals (fig 5). The barrier 18 prevents direct access to the terminals. The bait tube 20 may be removed from the trap whilst the lid is closed. The lid when shut closes a switch 22 to connect the power source (mains or battery) to the terminals. This switch acts as a cut off when the lid is open.

Title: L1 cache memory
Inventor: MULLA DEAN AHMAD
IPC: G06F12/08
Filed: 2001-02-20
Abstract: The cache 100 processes multiple access requests simultaneously by using separate queuing structures 206/209 for data and instructions, and uses ordering mechanisms that guarantee program order when there are address conflicts and architectural ordering requirements. The queuing structures are snoopable by other processors of a multiprocessor system. The cache has a tag access bypass 210 around the queuing structures, to allow for speculative checking by other levels of cache and for lower latency if the queues are empty. The cache allows for at least four accesses to be processed simultaneously. The results of the access can be sent to multiple consumers. The multiported nature of the cache allows for a very high bandwidth to be processed through this cache with a low latency.

Title: Microfluidic system for the manipulation and concentration of particles suspended in fluid
Inventor: BOER GERBEN
IPC: B01L3/00
Filed: 2001-05-11
Abstract: Voltage and pressure differences are applied across liquid channels so as to generate forces on the liquid in opposing directions. The cross section of the channels increases and decreases over a short distance at some locations 4, 5 along the channels so that vortices occur in the liquid flow where particles are retained by an appropriate combination of voltage and pressure differences. As described, a microfluidic system for the concentration of particulate matter comprises a first reservoir 1 containing a buffer solution, a second reservoir 2 containing an analyte, and a third reservoir 3 containing beads suspended in a liquid. Microchannels link the reservoirs and an expanded portion 4. Hydrostatic pressure is applied to the reservoir 3 containing the beads while an electro- osmotic force EOF is applied between the reservoir 1 and the reservoir 3 to establish counter flows of liquids. A vortex forms in the flared portion 5 due to the counter flow of the liquids and the beads are concentrated in the vortex. By switching the EOF between reservoirs 1 and 2 the buffer solution can be replaced by the analyte to enable an analysis to be performed.

Patent GB-2370894-A (GB)
Title: Updating firmware during operation
Inventor: BOLDON JOHN L
IPC: G06F9/445
Filed: 2001-10-18
Abstract: A laser printer (20) stores a compressed source copy of its operating system (OS1) in flash memory (25). Upon boot-up, the source copy is used to generate an active copy of the operating system that executes from RAM (23) for faster operation. A network management station (13) can transmit an upgrade operating system in compressed form over a network (AP1) to the printer, which treats the upgrade as another print job and places it in its job queue (30) in RAM. When the upgrade reaches the front of the queue, it is written to flash memory, overwriting the source copy of the active operating system. The active copy continues to process print jobs and handle network requests. When an idle state is detected, the active operating system resets the printer, purging itself from RAM. On re-initialization, the recently written source copy of the upgrade operating system is decompressed into RAM and becomes the new active operating system. A spare compressed copy (OS1'') of an operating system is maintained in flash memory in case the upgrade procedure fails. When an upgrade failure is detected, the spare operating system is used to generate the active operating system, pending another attempt at the upgrade procedure. The invention applies to application program upgrades as well as operating system upgrades.

Title: Data network with outputs delays to give constant time between input and output
Inventor: PAGE MICHAEL
IPC: H04L29/06
Filed: 2002-03-28
Abstract: A data processing network has client devices with a user interface and local real-time clocks for time stamping data processing actions or messages that are to be sent over the network. The network host has a real-time clock for time stamps and processes data dependent on the control setting of the user interfaces and the time stamps of the control setting messages. The network has a global clock for synchronising the client and host clocks. The host device and one of the client devices form a sending and receiving pair, the sending device transmitting a status message with a time stamp, indicating an adjustment to a setting, to the receiving device, the receiving device carrying out the data processing task dependent on the time stamp. Either of the host or the client devices can be the sending or the receiving device. The data processing task might be carried out at a time corresponding to the message time stamp plus a predetermined latency period which could depend on the user interface device type. The network could be used in a audio studio mixing desk to give equal time delays for actions from different controls desks.
