Title: Structure and method for sharing large databases
Inventor: CAZEMIER HENDRIK
IPC: G06F16/13
Filed: 2002-12-20
Abstract: The invention provides a sophisticated application programming mechanis m and technique that makes referencing data look as if the data is dynamically allocated by the process. The invention also provides a mechanism whereby all the persisted data is shared across all processes on the same computer that access it. In order to achieve these advantages, the invention creates small, process specific structures on demand as the program accesses the references from the persisted data and makes use of the underlying memory mapping and linking technologies inherent in modern Operation Systems. The technique is especially useful in large data warehouses, or planning data repositories, where it simplifies preparation for the sharing of non-volatil e data between instances of an application, permitting sharing of data between different applications, and reducing the size of the data shared. It allows for the data to be highly referenced internally while not requiring the extra memory used by pointer swizzling at runtime.

Abstract: In a protective garment, such as a firefighter's garment, of a type comprising an outer shell and a reflective strip, which is sewn to the outer shell, the reflective strip is spaced from the outer shell, except where the reflective strip is sewn to the outer shell, whereby to reduce risks of thread abrasion and to provide thermal insulation. The reflective strip may be thus spaced by a single strip interposed between two opposite margins of the reflective strip, along which margins the reflective strip is sewn to the outer shell, or by two spaced strips interposed therebetween. If two spaced strips are used, the reflective strip may be also sewn to the outer shell where the spaced strips are spaced from each other or, alternatively, the reflective strip is detached from the outer shell where the spaced strips are spaced from each other so as to define an air space between the reflective strip and the outer shell where the spaced strips are spaced from each other.

Inventor: HALLIWELL ROSS
IPC: G01R22/00
Filed: 2002-04-12
Abstract: A utility usage rate monitor that allows a utility consumer to monitor their current rate of consumption of a utility service. The monitor can display the rate of consumption in a form that has particular relevance to the consumer such as the cost or rate of expenditure on the utility or a greenhouse gas emission reduction rate. The monitor has a transducer (1) that senses the rate that the utility is being supplied to the consumer. The transducer produces a signal and sends it to a remotely located consumer interface (15) via a transmission link (16). An awareness of the expenditure or greenhouse gas emission associated with the current levels of consumption of the utility can motivate the consumer to modify their consumption habits and minimise wastage.
