Patent CA-2223932-A1 (CA)
Inventor: HUBBELL JEFFREY A
IPC: A61L27/38
Filed: 1996-06-05
Abstract: Cette invention se rapporte à des hydrogels à polymérisation lente, qui sont utiles comme moyen pour administrer de grandes quantités de cellules isolées par injection. Ces gels stimulent la prise de greffes et fournissent des matrices tridimensionnelles pour la croissance de nouvelles cellules. Le tissu qui en résulte est de composition et d'histologie similaires à celles des tissus existants à l'état naturel. Ce procédé peut être utilisé pour une grande variété de techniques de reconstruction, y compris le moulage personnalisé d'implants cellulaires destinés à reconstruire des structures tissulaires tridimensionnelles lésées, ainsi que l'implantation de tissus, d'une manière générale. Ces polymères permettent la construction de tissus musculaires et cartilagineux qui sont utiles pour réparer des défauts tels que le reflux et l'incontinence.

Title: Method and apparatus for spectral analysis in a disk recording system
Inventor: FITZPATRICK JAMES
IPC: G11B5/09
Filed: 1997-04-23
Abstract: A method of performing spectral analysis of signals recorded by a magnetic recording or storage system is provided using a modified channel chip of the system. The modified channel chip enables measurement of harmonic components of the recorded signal. The method is performed by reading the recorded periodic analog signal and converting the signal into a discrete time periodic signal. The discrete time periodic signal is digitally sampled at predetermined intervals, and the digital samples are selectively accumulated in a register (341) or registers of the channel chip. Incoming digital samples are accumulated by alternately being added and substracted (345) to contents of single register (341). The accumulated results represent summations used to determine harmonic coefficients of the recorded signal. The harmonic sensor includes an arithmetic unit and a register (341) or register for accumulating the digital samples.

Patent CA-2250807-A1 (CA)
Title: Vehicle arresting units and fabrication methods
Inventor: ANGLEY RICHARD D
IPC: E01C9/00
Filed: 1998-02-06
Abstract: Vehicle arresting blocks of cellular concrete (70) are usable to safely slow travel of an object and may be used to construct an aircraft arresting bed at the end of an airport runway. For such purposes, cellular concrete blocks (70) must be fabricated to exhibit compressive gradient strengths of predetermined values to provide sufficient, but not excessive, deceleration forces on an object. Material uniformity characteristics must be met to avoid unacceptable drag force variations, so that arresting blocks desirably exhibit a predetermined compressive gradient strength (e.g., a 60/80 CGS) over a depth of penetration of 10 to 66 percent of block thickness (Fig. 7). A 60/80 CGS will typically represent an average compressive strength of 70 pounds per square inch over such depth of penetration. Prior applications of cellular concrete typically involved meeting minimum strength values and the production methods did not meet uniformity or compressive gradient strength predictability as required for arresting blocks. Described methods include parameter, ingredient and process controls and ranges effective to enable fabrication of arresting blocks having dry densities and compressive gradient strengths which can be specified in order to provide limited deceleration of aircraft and other objects.  Limited deceleration can avoid destructive effects inherent in excess rates of deceleration.

Title: Automatic wireless alerting on an automatic call distribution center
Inventor: CHAVEZ DAVID L JR
IPC: H04M3/523
Filed: 1999-02-09
Abstract: Allowing the alerting of supervisors and off duty agents to conditions on a split of an ACD system via wireless terminals. The conditions under which the wireless alerting will be performed are programmed by the owner of the ACD system rather than the manufacturer. The ACD center is connected to a wireless switching system via a primary rate ISDN interface (PRI) link. The ACD system considers the wireless switching system as another ACD system and utilizes the look ahead interflow operation to communicate information to the wireless switching system concerning the condition of a split. This is done by the ACD placing informational telecommunication calls to pseudo telecommunication numbers via the PRI link to the wireless switching system. The wireless switching system is responsive to each of these pseudo numbers to interpret the pseudo number as to the wireless terminal that should be contacted and an alphanumeric message that is to be displayed on that wireless terminal. The alphanumeric message defines the condition of the split to the supervisor or off duty agents of the split. The wireless switching system may be a wireless telephone system or a paging system. The wireless terminals may be wireless telephones or pagers.
