Title: Networked apparatus with address card
Inventor: CAPALDI-TALLON ALAN
IPC: G06K19/06
Filed: 2007-11-14
Abstract: The invention is in the field of addressable networked devices, particularly those devices where the address is provided through passive mechanical means. Applications of the networked devices include alarm systems, particularly fire alarms, smoke alarms and intruder alarms. An electronic apparatus 101 is arranged to communicate with like apparatus over a network in which each apparatus has its unique address. The electronic apparatus comprises a rectangular recess 203 with a slot-shaped opening for receiving endwise a rectangular address card 504 and having side rails for guiding the address card as it is slid into the recess, mechanical reading means for reading each digit of a binary address from a corresponding number of tabs 503 selectively projecting from the plane of the address card, each representing a different digit of the binary address; and electromechanical transducing means for determining the address from the reading means to determine a unique address for the apparatus set by the card. The side rail or rails are each channel-shaped to constrain the address card 504 to lengthwise translational motion and comprise an elongate flange parallel to the plane of the recess for overlying a corresponding marginal edge of an address card in use. The address card 504 is repeatedly configurable to change the address of the apparatus by moving the tabs 503.

Title: Video Camera with Low Power Imminent Event Detection
Inventor: SMITH BRIAN DAVID VINCENT
IPC: G06V10/22
Filed: 2008-05-01
Abstract: Video system 1 having image sensor 2, low power imminent event detector 6 for receiving and processing images from the image sensor 2 to generate an event signal when an imminent event is detected and a higher power main event processor 8 to receive and analyse images from the image sensor 2 to extract information (e.g. vehicle registration plate numbers) and having a dormant mode in which it consumes little or no power, and an active mode, activated by the event signal, in which it analyses the images. An event signal may not be generated when changes to the image are large, indicating that the sensor itself is moving or below a difference threshold indicating the change is due to noise. An illumination source 4 and transmitter may also be activated by the event signal and the settings for the image sensor may be altered for optimum capturing of the event. A buffer 10 may be provided to store data when the processor 8 is powering up or cannot analyse the image data as quickly as it is output from sensor 2. The system may be powered by a solar panel.

Title: Fluid pressure regulator
Inventor: FISHWICK JAMES
IPC: F16K31/126
Filed: 2008-10-08
Abstract: The flow of fluid to a fluid actuator is controlled using a fluid pressure regulator 20 to regulate the pressure of fluid supplied to a downstream actuator. Intermediate the regulator and the actuator there is at least one fluid flow restriction downstream of the pressure regulator and upstream of the actuator. The fluid pressure regulator 20 has an inlet 37 and an outlet 38, a flow path between which is interrupted by a valve 45 movable between an open and a closed position in order to vary the flow from the inlet to the outlet. A control chamber 42 of the regulator has a diaphragm assembly 43 responsive to pressure changes across it to regulate the position of the valve. A control force is applied to a first side of the diaphragm assembly and a fluid pressure is applied to a second side of the diaphragm assembly. The fluid pressure is derived from a location in the system downstream of the at least one flow restriction and upstream of the actuator and is fed through a fluid feed port in the housing wall of the regulator.

Patent GB-2465772-A (GB)
Title: Analysing memory accessed by an application
Inventor: CARTY CHRISTOPHER
IPC: G06F11/14
Filed: 2008-11-27
Abstract: In a method of analysing memory accessed by a first application, the access attribute of each page of memory under analysis is set to be read-only, so as to force an interrupt if the first application attempts to modify the contents of a memory page, said interrupt passing control from the first application to a second application. The second application duplicates the contents of the memory page to storage and then sets the access attribute of the memory page to allow the first application to modify its contents. In this way, only those pages of memory that have been changed are archived, thereby significantly reducing memory and computational load. The supervisory computational load is further reduced as it takes advantage of existing read/write checks. A record of the current and previous memory states of the memory system is thus obtained for a significantly smaller load on resources.

Title: Base-assisted formation of tin-sucrose adducts
Inventor: SEABERG PETER J
IPC: A23L27/30
Filed: 2009-10-23
Abstract: A method of forming a sucrose-6-ester includes in sequence the steps of:a) contacting sucrose with a organotin-based acylation promoter in a solvent in the presence of a base selected from amines and basic alkali metal salts;b) removing water to form a tin-sucrose adduct; and contacting the tin-sucrose adduct with an acylating agent to form the sucrose-6-ester. The sucrose-6-ester may then be converted to sucralose. The base may be selected from alkali metal carbonates, bicarbonates, hydroxides, tribasic phosphates, dibasic phosphates, carboxylates and N,N-disopropylamine. The preferred organotin-based acylation promoter is 1,3-diacetoxy-1,1,3,3-tetrabutyldistannoxane (DSDA). The preferred acylating agent is acetic anhydride. The solvent is preferably a tertiary amide such as dimethylformamide (DMF), although it is preferred that cyclohexane is also present. The cyclohexane can be removed by azeotropic distillation using a Dean-Stark trap. The sucrose-6-ester can be converted to sucralose, which can then be purified.
