Patent CA-2439805-A1 (CA)
Inventor: BRISCOE ROBERT JOHN
IPC: H04L29/06
Filed: 2002-03-07
Abstract: A method of operating a packet network to provide selectable levels of service to different communications flows is disclosed. The method provides a network user with more flexibility in assigning a level of service to a given flow than conventional Asynchronous Transfer Mode networks. Furthermore, it provides a better differentiation between different qualities of service than is enabled by recent proposals for Internet Protocol networks. By identifying packets belonging to flows requiring a relatively high level of service, and, in response, allowing those packets access to capacity which is otherwise withheld, a relatively high level of service can be provided to streams of such packets. The invention is especially useful in relation to providing selected flows along residential high-speed Internet access lines (e.g. ADSL) with a higher level of capacity than other flows. The withheld capacity can comprise capacity which is normally hidden from the end-user by network configuration. The sender and/or receiver of a flow can be charged for the high level of service provided to that flow.

Abstract: A joint device for a leg guard, particularly for a leg guard used by ice-hockey players, comprises a first part that covers the wearer's lower leg, and a second part (2) that covers a part of the wearer's thigh above the knee and that is pivotally connected to the first part (1) via a joint element (4). A  cup-shaped third part (3) bridges the gap between the first and the second parts (1, 2) and is pivotally mounted (5) on the second part (2). The joint element (4) includes pins which engage in a slot or groove (11) on the sides of the third part (3), so that the third part (3) will be dogged by the second part (2) when the angle between the first and the second parts is smaller than a limit angle. The first part (1) includes pins (8) which engage in a second slot (10) in the third part (3). The second slots include a first circular section whose center lies in the first joint element (4) when the guard is at a more pronounced angle than the limit angle. The second slot (10) has a second section (10b) that extends form the lower end of the first section (10a) in a direction radially away from the second joint elements. When the first and the second parts (1, 2) define an angle that is smaller than the limit angle,the third part (3) and the portions (21, 32) of respective first and second parts overlapped by said third part (3) have generally the same radius of curvature and common centre of curvature in the first joint element (4).

Title: Down hole gas analyzer method and apparatus
Inventor: HUNZIKER JAMES C
IPC: E21B49/08
Filed: 2002-04-16
Abstract: A logging while drilling and wire line system (10) for analyzing the concentration of carbon dioxide or another substance, in a sample down hole in a bore hole (12). A chamber (20) is filled with a sample that may be fluid, or condensate and gas. The interior chamber volume (22) is selectably expandable for decompression of the sample. The sample may alternately be decompressed by allowing a sample at formation pressure to enter the chamber at a lower pressure, thereby decompressing the sample. A sensor (28) measures the absorbance, transmittance or attenuated total reflectance of the infrared light. Mid and near infrared light is utilized to identify carbon dioxide, water and a plurality of hydrocarbons. A wiper cleans the transmitter (26) and sensor between readings to reduce measurement error caused by fluid sample contamination.
