Title: Chemical cleaning of biological material
Inventor: CARR ROBERT M JR
IPC: A61K35/12
Filed: 1998-05-08
Abstract: The invention is directed to collagenous tissues which have been treated to remove non-collagenous components such as cells, cellular debris, and other extracellular matrix components, such as proteoglycans and glycosaminoglycans, normally found in native tissues.  Treatment of the tissue with alkali, chelating agents, acids and salts removes non-collagenous components from the collagenous tissue matrix while controlling the amount of swelling and dissolution so that the resultant collagen matrix retains its structural organization, integrity and bioremodelable properties. The process circumvents the need to use detergents and enzymes which detrimentally affect the cell compatibility, strength and bioremodelability of the collagen matrix. The collagenous tissue matrix is used for implantation, repair, or use in a mammalian host.

Title: Sterilizable cultivation system with separately attachable microfiltration membrane
Inventor: HSU WEI K
IPC: C12M1/00
Filed: 2000-02-22
Abstract: A sterilizable cultivation system is provided for growing selected organisms for use in biological applications and the cultivation edible fungi. A  sealable, sterilizable container holds a growth substrate in a sterile condition. A  separate, adhesive vent filter is provided, which is adhereable to a vent opening in the container. The vent filter is gas permeable and allows gas exchange between the interior of the container and the ambient environment, but prevents the passage of microbes and other organisms into or out of the container. This gas exchange prevents excess carbon dioxide from accumulating in the container and allows necessary oxygen into the container in order to maintain an appropriate growth environment for the selected organisms. The vent filter may be combined with the container (a) during manufacture of new containers, or (b) in the field by the end-user on new containers or on re-cycled containers. The separately provided vent filters allow the end-user to adjust certain parameters of the growth environment within the container in the field. This is accomplished by adjusting the venting characteristics of the cultivation system, by increasing or reducing the amount and quality of the vent filters on the container.
Patent CA-2300796-A1 (CA)
Inventor: TAHARA KAZUSHI
IPC: H04L25/03
Filed: 2000-03-15
Abstract: The adder subtracts the estimated echo from the input symbol to generate the demodulated symbol, and the Trellis decoder applies Trellis decoding onto the demodulated symbol to generate maximum likelihood transmission symbol sequence. The feedback register stores estimated transmission symbol values for a feedback filter, and A coefficient register stores coefficient values for the feedback filter. The feedback register updating unit generates the estimated transmission symbol and the estimated transmission symbol value corresponding to the next time point based on the demodulated symbol, the maximum likelihood transmission symbol sequence and the estimated transmission symbol corresponding to a current time point, and updates the values stored in the feedback register by using the estimated transmission symbol value corresponding to the next time point.      The coefficient updating unit updates the values stored in the coefficient register based on the demodulated symbol and the estimated transmission symbol. The estimated echo calculator calculates the estimated echo based on the values stored in the feedback register and the values stored in the coefficient register.

Title: Well casing assembly with erosion protection for inner screen
Inventor: UBAN STEPHEN A
IPC: B01D46/24
Filed: 1998-09-03
Abstract: Well casing assembly (20) for use in oil and gas wells, and especially deviated or horizontal wells, has an inner pipe member (22) with threaded ends (22') which permit a number of casing assemblies to be joined in a string. The inner pipe (22) has a serie of perforations (40) along a segment (42) of its length which are covered by an elongated screen member (64) which prevents the passage of sand particles. A concentric outer protective cover member (24) is devoid of perforations (50) in regions which are radially opposite the inner screen (64) to prevent damage to the screen. One or more perforated segments (52, 52') of the outer member (24) are axially spaced from the screen member (64) so that inward flow from a formation will have its energy and velocity reduced before it reaches the screen, thereby minimizing erosion of the screen surface. If desired, perforated flow control devices such as annular rings (82) can be located between the inner pipe (22) and outer member (24) at the ends of the screen segment to allow a more uniform flow to the screen, and thus further reduce erosion.

Patent CA-2318724-A1 (CA)
Inventor: ARAVAMUDAN MURALI
IPC: H04M7/00
Filed: 2000-09-13
Abstract: A method is disclosed for designing a signaling network of call coordinators (CCs) for Internet telephony. The new method can be used to design a CC  network of arbitrary size that satisfies, with high probability, limitations on the maximum number of sockets per CC and on the maximum number of hops between an arbitrary pair of switches in the network. According to the disclosed method, the network of CCs is treated initially as a collection of isolated points, one point for each CC. Then, links are added between pairs of CCs, excluding pairs lying within the same switch. The links are added randomly, but with a particular probability p, which may be different for different pairs. Thus, whether a given link is added depends, in effect, upon the outcome of a loaded coin toss in which the probability of a positive outcome is p.

Abstract: A CDMA baseband receiver includes a first correlating unit, a long code phase candidate outputting section and a long code determining section. The first correlating unit calculates first correlation values from a spread modulation signal and a short code which is common to base stations. The long code phase candidate outputting section outputs selected long code phase candidates corresponding to ones selected from the first correlation values, based on the spread modulation signal, and determined long codes. The selected long code phase candidates are other than long code phase candidates for known ones of the base stations. The long code determining section generates the determined long codes for unknown ones of the base stations from the spread modulation signal, the short code, and long codes generated based on the selected long code phase candidates. Each long code is peculiar to one base station.
Patent CA-2331611-A1 (CA)
Inventor: SMITH WILLIAM P
IPC: H04B14/04
Filed: 1996-11-21
Abstract: A subband audio coder (12) employs perfect/non-perfect reconstruction filters (34), predictive/non-predictive subband encoding (72), transient analysis (106), and psycho-acoustic/minimum mean-square-error (mmse) bit allocation (30) over time, frequency and the multiple audio channels to encode/decode a data stream to generate high fidelity reconstructed audio. The audio coder windows (64) the multi-channel audio signal such that the frame size, i.e., number of bytes, is constrained to lie in a desired range, and formats the encoded data so that the individual subframes can be played back as they are received thereby reducing latency. Furthermore, the audio coder processes the baseband portion (0-24kHz) of the audio bandwidth for sampling frequencies of 48kHz and higher with the same encoding/decoding algorithm so that audio coder architecture is future compatible.
