Title: System and method for executing verifiable programs with facility for using non-verifiable programs from trusted sources
Inventor: MCMANIS CHARLES E
IPC: G06F9/44
Filed: 1996-11-18
Abstract: A computer system includes a program executer that executes verifiable architecture neutral programs and a class loader that prohibits the loading and execution of non-verifiable programs unless (A) the non-verifiable program resides in a trusted repository of such programs, or (B) the non-verifiable program is indirectly verifiable by way of a digital signature on the non-verifiable program that proves the program was produced by a trusted source. In the preferred embodiment, verifiable architecture neutral programs are Java bytecode programs whose integrity is verified using a Java bytecode program verifier. The non-verifiable programs are generally architecture specific compiled programs generated with the assistance of a compiler. Each architecture specific program typically includes two signatures, including one by the compiling party and one by the compiler. Each digital signature includes a signing party identifier and an encrypted message. The encrypted message includes a message generated by a predefined procedure, and is encrypted using a private encryption key associated with the signing party. A digital signature verifier used by the class loader includes logic for processing each digital signature by obtaining a public key associated with the signing party, decrypting the encrypted message of the digital signature with that public key so as generate a decrypted message, generating a test message by executing the predefined procedure on the architecture specific program associated with the digital signature, comparing the test message with the decrypted message, and issuing a failure signal if the decrypted message digest and test message digest do not match.
Patent CA-2191456-A1 (CA)
Inventor: FOSTER ROBERT F
IPC: C23C16/458
Filed: 1994-11-29
Abstract: Low temperature deposition of CVD and PECVD films utilizes a gas-dispersing showerhead (36) position within one inch of a rotating substrate. The showerhead is positioned a suitable distance below a gas-dispensing ring (50, 52) such a steady state flow of gas develop, between the ring and showerhead. A cylindrical structure extends between the gas-dispersing ring and a showerhead to contain the gas over the showerhead yielding a small boundary layer over the substrate. The showerhead is biased with RF energy such that it acts as an electrode to incite a plasma proximate with the substrate for PECVD. The cylinder (60) is isolated from the showerhead such as by a quartz insulator ring (62) to prevent ignition of a plasma within the cylinder, or alternatively, the cylinder is fabricated of quartz material. The RF showerhead utilizes small gas-dispersing holes (54) to further prevent ignition of a plasma within the cylinder.

Title: Control symbol and data symbol guard intervals with different time lengths in cofdm transmission frames
Inventor: WECK CHRISTFRIED
IPC: H04L27/26
Filed: 1995-07-20
Abstract: In order to prevent wanted signal capacity from being reduced during OFDM  modulation of digital coded data, control symbol protecting intervals in the frame head of each OFDM transmission frame are larger than data symbol protecting intervals in wanted data areas of each OFDM transmission frame. The length of data symbol protecting intervals is determined during demodulation and data symbol scanning times are then determined depending on the thus determined length of the protecting intervals.

Title: Gas turbine subassembly having a brush seal
Inventor: DINC OSMAN S
IPC: F02C7/28
Filed: 1997-04-17
Abstract: A gas turbine subassembly having a stator, a rotor, and an annular brush seal which is attached to the stator and whose free end is in line-to-line contact with a first circumferential portion of the rotor's outside surface during a first rotation/load state (such as a full-speed/full-load state of a power-plant gas-turbine rotor). A longitudinally-adjoining second circumferential portion (such as a groove) has a smaller diameter than that of the first circumferential portion. The rotor and stator together undergo a predetermined differential thermal movement when the rotor transitions to a second rotation/load state (such as a turning-gear/no-load state).      During such movement, the free end of the brush seal moves radially inward and longitudinally across the second portion, preferably without any contact, to minimize or eliminate brush seal wear.

Patent CA-2205370-A1 (CA)
Inventor: CAIN FRASER
IPC: G06F1/00
Filed: 1995-11-15
Abstract: A system for locating and monitoring electronic devices utilizing a security system that is secretly and transparently embedded within the software, firmware, or hardware of a computer. This security system causes the client computer to periodically and conditionally call a host system to report its serial number via an encoded series of dialed numbers. A host monitoring system receives calls from various clients and determines which calls to accept and which to reject. This determination is made by comparing the decoded client serial numbers with a predefined and updated list of numbers corresponding to reported stolen computers. Only calls from clients on the predefined list are accepted. The host also concurrently obtains the caller ID  of the calling client to determine the physical location of the client computer. The caller ID, indicating the physical location of the stolen device, and the serial number are subsequently transmitted to a notifying station in order to facilitate the recovery of the stolen device. The security system remains hidden from the user, and actively resists attempts to disable it.

Title: Cdma transmission employing clipping function
Inventor: BHAGALIA SHASHIKANT
IPC: H04J13/00
Filed: 1996-06-03
Abstract: A CDMA signal processing circuit (300) includes a summer circuit (302) that receives a plurality of CDMA signals from a plurality of channels (304). The summer circuit (302) combines the plurality of CDMA signals according to a power magnitude value and power direction value associated with each CDMA signal. The summer circuit (302) generates a summed signal (306) that is applied to a clipping circuit (308). The clipping circuit (308) removes a portion of the summed signal (306) outside a desired threshold range and generates a clipped signal (310) therefrom. Digital to analog processing circuits (312 and 314) convert the clipped signal (310) into a half width encoded format. Digital to analog processing circuits (312 and 314) transform the half width encoded clipped signal into analog I and Q signals, respectively. The analog I and Q signals are applied to corresponding filters (316 and 318) prior to transmission.
