Patent number: 8304275Abstract: A MEMS device assembly (20) includes a MEMS die (22) and an integrated circuit (IC) die (24). The MEMS die (22) includes a MEMS device (36) formed on a substrate (38) and a cap layer (34). A packaging process (72) entails forming the MEMS device (36) on the substrate (38) and removing a material portion of the substrate (38) surrounding the device (36) to form a cantilevered substrate platform (46) at which the MEMS device (36) resides. The cap layer (34) is coupled to the substrate (38) overlying the MEMS device (36). The MEMS die (22) is electrically interconnected with the IC die (24). Molding compound (32) is applied to substantially encapsulate the MEMS die (22), the IC die (24), and interconnects (30) that electrically interconnect the MEMS device (22) with the IC die (24).

Patent number: 8296086Abstract: A new measurement system, with two receiver channels per measurement port, has been developed that provides absolute magnitude and absolute phase relationship measurements over wide bandwidths. Gain ranging is used at RF to provide optimum noise performance and a swept YIG preselector filter is used to avoid spurious signals. A new absolute vector error correction method is used to calibrate the measurement system in order to allow for absolute vector measurements, and it also removes the time-varying responses caused by the swept YIG preselector filters. A quasi-reciprocal mixer with a characterized non-reciprocal ratio is used to provide the absolute calibration standard. The two receiver channels can be adapted to a wide variety of applications, including wide bandwidth vector signal analyzer measurements, mixer measurements, and harmonic measurements. The two-channels can also be used as an absolute calibrated transmitter/reflectometer.Type: GrantFiled: March 9, 2012Date of Patent: October 23, 2012Inventors: Ben K. Sternberg, Steven L. Dvorak

Patent number: 8259779Abstract: A wireless network (20) with at least a first radio communication unit (24) and a second radio communication unit (26) transmits and receives signals with minimal interference from the surrounding environment of the first unit (24) and second unit (26). The first radio communication unit (24) determines frequencies (54) having power level above a threshold (52), and creates a list of these frequencies (50) to be transmitted to the second radio communication unit (26). The second radio communication unit (26) places notches (140) in its transmission band (88) based on frequencies (54) in the list (50), reserved frequencies (132), and local frequencies (92) having signal energy above a threshold (90).

Patent number: 8219488Abstract: The present invention relates to the field of e-commerce and in particular to making purchases on-line using payment card, for example debit, charge or credit cards. The concept of the present invention adopts an alternative approach to security methods presently employed to protect cardholders. The concept obviates the need for a cardholder to transmit Card Numbers along with other purchasing details at the time of purchase and couples this with the use of a password feature. This renders the transaction akin to a Bank Cash withdrawal that Bank/card Schemes are totally happy with from a security point of view but are reluctant to allow e-commerce and/or any others access to their “network” to ensure Security.Type: GrantFiled: June 4, 2002Date of Patent: July 10, 2012Inventor: Gerard J. Barry

Patent number: 8184812Abstract: A secure computing device (14) includes a secure processing section (30) having a tamper detection circuit (58) and a monotonic counter (68). The tamper detection circuit (58) detects an event which suggests that the trust associated with the secure processing section (30) may have been compromised. When such an event is detected, a security breach is declared and trusted software (38) is disabled. After a security breach is declared, the monotonic counter (68) may be reclaimed. The monotonic counter (68) provides a monotonic count value (70) that includes an LSB portion (80) and an MSB portion (82). The LSB portion (80) is obtained from a binary counter (72). The MSB portion (82) is obtained from a register (84) of independent one-time-programmable bits. The monotonic counter (68) is reclaimed by programming one of the one-time programmable bits to guarantee that future counting of the monotonic counter will be monotonic relative to all past counting.Type: GrantFiled: June 3, 2009Date of Patent: May 22, 2012Assignee: Freescale Semiconductor, Inc.Inventors: Evgeni Margolis, Thomas E.

Patent number: 8185065Abstract: A transmitting unit (12) clips a communication signal (14) to form a threshold-responsive signal (36, 36?) which includes in-band distortion (40) and out-of-band distortion (38). A portion of the out-of-band distortion (38) is notched within rejection bands (48, 50) adjacent to the communication signal's bandwidth (24). But remaining portions of the out-of-band distortion (38) and portions of the in-band distortion (40) are included with the communication signal (14). The remaining portion of the out-of-band distortion (38) causes the communication signal (14) to be in violation of a spectral mask (30). The mask-violating communication signal 14 with out-of-band distortion (38) and in-band distortion (40) is amplified by an RF power amplifier (22). After amplification, a bandpass filter (92) exhibiting fast rolloff regions (110) attenuates the amplified out-of-band distortion (38) causing compliance with the spectral mask (30).Type: GrantFiled: October 15, 2009Date of Patent: May 22, 2012Assignee: CrestCom, Inc.Inventors: Ronald Duane McCallister, Eric M.

Patent number: 8149564Abstract: A MEMS capacitive device (90) includes a fixed capacitor plate (104) formed on a surface (102) of a substrate (100). A movable capacitor plate (114) is suspended above the fixed capacitor plate (104) by compliant members (116) anchored to the surface (102). A movable element (120) is positioned in spaced apart relationship from the movable capacitor plate (104) and has an actuator (130) formed thereon. Actuation of the actuator (130) causes abutment of a portion of the movable element (120) against a contact surface (136) of the movable plate (114). The abutment moves the movable plate (114) toward the fixed plate (104) to alter a capacitance (112) between the plates (104, 114). Another substrate (118) may be coupled to the substrate (100) such that a surface (126) of the substrate (118) faces the surface (102) of the substrate (100).
