Title: Strain-stabilized birefringent crystal
Inventor: MCLEOD ROBERT R
IPC: G02B5/30
Filed: 2001-10-04
Abstract: The invention provides an optical system for use in a stable, temperature-insensitive birefringent crystal interferometer (BCI). The optical system includes a first block of light transmissive birefringent material having an input port and an output port, the material having in the spectral region of desired device operation a net retardance at a first temperature, and straining means for inducing a strain in one of the first block and a second block of light transmissive material optically coupled to the first block, the strain induced for maintaining the net retardance substantially unchanged from the net retardance at at least a second other temperature. Advantageously, the optical system uses a single variety of crystal, which is cheaper, more robust, and has better performance than BCIs having two crystal varieties.

Title: Wide band radio transmission method
Inventor: PARK DONG-SEEK
IPC: H04W4/00
Filed: 2000-10-19
Abstract: A wide band radio transmission method for transmit-ting bit streams of a video-related application through a radio channel is provided. The wide band radio transmission method comprises the steps of: (a) obtaining identification information on a video-related application which is executed in a user layer, from the user layer; (b) obtaining information on at least one of channel characteristics and a decoding state from a physical layer; and (c) deciding on a quality of service (QoS) level with reference to the identification informa-tion and the information on at least one of the channel characteris-tics and the decoding state from the physical layer. The wide band radio transmission method can efficiently support video-related ap-plications such as applications of H.324M standard, H.323 standard, H.320 standard, and MPEG-4 standard. Also, negotiations on video services having different quality of service (QoS) levels can be per-formed, and then, optimum video services considering channel char-acteristics can be provided.
Patent CA-2362537-A1 (CA)
Inventor: FERNANDES LUIZ CLAUDIO VIEIRA
IPC: F02C3/04
Filed: 2001-11-01
Abstract: The invention provides detailed information about a system and method of obtaining clean hot air for portable air heaters. This invention incorporates several new concepts and it basically describes the use of a novel concept that uses a turbocharger that produces mechanical energy to be directly or indirectly transferred to the process air. The excess turbocharger mechanical energy is used to drive a small electrical generator that can drive small ancillary equipment. For start-up conditions only, a small air fan will drive both combustor and turbocharger. Advantages of this invention over existing portable air heaters are smaller size and weight, clean combustion, higher overall efficiency, lower costs, potential to deliver air at much higher pressure and temperatures and a much larger range of air flow operation.

Inventor: AKERBERG DAG
IPC: H04B1/707
Filed: 2000-02-15
Abstract: A first telecommunications system (201), with radio transmission access utilizing code division multiple access (CDMA) with a time division multiple access (TDMA) component, has at least partially geographically overlapping coverage with a second telecommunications system (202), base station (BS) of the first system communicates over an air interface with a subscriber station (SS) and broadcasts a common broadcast physical channel (BPCH) including broadcast system identity information on at least an active carrier/timeslot combination (C/TS). The subscriber station uses the broadcast system identity information to distinguish between transmissions of the two telecommunications systems, and for framing transmissions in the first system. The base station of the first system broadcasts at least two common broadcast physical channels active on different timeslots. Preferably, a fixed direct sequence CDMA code is employed for the common broadcast physical channel. In accordance with an instant dynamic channel selection procedure of the present invention, the subscriber station selects a carrier/timeslot for sending an access request to the first system base station. The carrier/timeslot selected is also used for a traffic channel and is preferably a least interfered carrier/timeslot. In response to the access request, the first system base station sends an answer on a next down-link carrier/timeslot included in a duplex pair with the selected carrier/timeslot. At any given moment a connection between the first system base station and the subscriber station is borne on a physical channel of the first telecommunications system, the physical channel being defined by a code, timeslot, and frequency.

The process includes a forward flow stage which comprises (a) passing the feed gas into a first adsorption zone containing an adsorbent selective for the adsorption of nitrogen over oxygen and argon, and withdrawing therefrom a nitrogen-depleted intermediate gas; (b) passing the nitrogen-depleted intermediate gas into a second adsorption zone containing an adsorbent which is selective for the adsorption of nitrogen over argon and selective for the adsorption of argon over oxygen; (c) withdrawing an oxygen- enriched product gas from the second adsorption zone; and (d) terminating the passing of feed gas into the first adsorption zone and withdrawing an oxygen- enriched depressurization gas from the second adsorption zone in the same flow direction as (c). During (a) or during (d), nitrogen breakthrough from the first adsorption zone can occur and nitrogen can be adsorbed in the second adsorption zone. Also disclosed is a multi-zone adsorber for use in such a process.
