Patent number: 7939932Abstract: A low-temperature inorganic dielectric ALD film (e.g., Al2O3 and TiO2) is deposited on a packaged or unpackaged chip device so as to coat the device including any exposed electrical contacts. Such a low-temperature ALD film generally can be deposited without damaging the packaged chip device. The ALD film is typically deposited at a sufficient thickness to provide desired qualities (e.g., hermeticity for the entire packaged chip device, passivation for the electrical contacts, biocompatibility, etc.) but still allow for electrical connections to be made to the electrical contacts (e.g., by soldering or otherwise) directly through the ALD film without having to expose the electrical contacts.Type: GrantFiled: June 20, 2008Date of Patent: May 10, 2011Assignee: Analog Devices, Inc.Inventor: John R.

Publication number: 20100285628Abstract: A micromachined microphone is formed from a silicon or silicon-on-insulator (SOI) wafer. A fixed sensing electrode for the microphone is formed from a top silicon layer of the wafer. Various polysilicon microphone structures are formed above a front side of the top silicon layer by depositing at least one oxide layer, forming the structures, and then removing a portion of the oxide underlying the structures from a back side of the top silicon layer through trenches formed through the top silicon layer. The trenches allow sound waves to reach the diaphragm from the back side of the top silicon layer. In an SOI wafer, a cavity is formed through a bottom silicon layer and an intermediate oxide layer to expose the trenches for both removing the oxide and allowing the sound waves to reach the diaphragm. An inertial sensor may be formed on the same wafer, with various inertial sensor structures formed at substantially the same time and using substantially the same processes as corresponding microphone structures.Type: ApplicationFiled: July 16, 2010Publication date: November 11, 2010Applicant: Analog Devices, Inc.Inventors: John R. Martin, Timothy J. Brosnihan, Craig Core, Thomas Kieran Nunan, Jason Weigold, Xin Zhang

Publication number: 20100279804Abstract: A virtual shuffleboard table gaming apparatus including a housing having a playing field, a game acquisition circuit, and a display. As a puck is propelled towards a puck return at the distal end of the playing field, the puck temporarily obstructs at least two beams from transmitters. Sensors that receive the transmitted beams provide information to the game acquisition circuit indicative of the time when the beams were blocked and unblocked. The duration of time the beams are block are used by a game controller to calculate the angle of travel, location, and velocity of the puck. This information is then used by the game controller to determine the travel path and resting place of a virtual puck on a virtual playing field, as well as determine whether the virtual puck rests in a scoring zone and maintain a game score.Type: ApplicationFiled: June 25, 2010Publication date: November 4, 2010Applicant: Arachnid, Inc.Inventors: John R.

Patent number: 7821084Abstract: Rather than increasing the mass of the structure, the structure in a sensor system suspends its substrate from some mechanical ground. Motion of the substrate relative to the mechanical ground thus provides the movement information. To those ends, the sensor system includes a base, a substrate, and a flexible member suspended from at least a portion of the substrate. At least a portion of the flexible member is capable of moving relative to at least a portion of the substrate. In addition, the flexible member is secured to the base, thus causing the substrate to be movable relative to the base. Moreover, the mass of the substrate is greater than the mass of the flexible member. The substrate and flexible member are configured to interact to produce a motion signal identifying movement of the base.Type: GrantFiled: December 7, 2007Date of Patent: October 26, 2010Assignee: Analog Devices, Inc.Inventors: John R.

Patent number: 7595633Abstract: A method and a system for measuring the velocity of a projectile. The method and system employ sensors that uses magnetoresistive sensing elements to measure the velocity of a projectile. Two magnetoresistive based sensors may be used to sense a time at which a projectile crosses a sense path associated with each of the sensors. Because the sensors employ magnetoresistive sensing elements, high quality voltage signals are produced, allowing accurate time measurements to be calculated. Accordingly, the velocity of the projectile can be determined by using these time measurements along with a measured spacing distance between the sensors.Type: GrantFiled: February 8, 2007Date of Patent: September 29, 2009Assignee: Honeywell International Inc.Inventors: John R. Martin, William M. Blevins

Patent number: 7563632Abstract: A die has a part that is sealed with a cap. The seal can be hermetic or non-hermetic. If hermetic, a layer of glass or metal is formed in the surface of the die, and the cap has a layer of glass or metal at a peripheral area so that, when heated, the layers form a hermetic seal. A non-hermetic seal can be formed by bonding a cap with a patterned adhesive. The cap, which can be silicon or can be a metal paddle, is electrically coupled to a fixed voltage to shield the part of the die.Type: GrantFiled: October 30, 2007Date of Patent: July 21, 2009Assignee: Analog Devices, Inc.Inventors: John R.

Publication number: 20090131186Abstract: A method for play of a parlor entertainment unit including a remote activation assembly and an activation-sensing unit. The activation-sensing unit, which may be battery operated and housed in the entertainment unit, may be in an energy-conserving sleep mode until the activation-sensing unit receives a wake-up signal. In one embodiment, the wake-up signal may be generated by the engagement of an activation mechanism, such as a coin slide. After being awoken, the activation-sensing unit may transmit an inquiry to the remote activation assembly as to whether the associated entertainment unit has been selected for play and/or whether there is a sufficient number of credits available for play. If that entertainment unit has not been selected for play, the activation-sensing unit may return to a sleep mode. However, if sufficient play credits are available for the entertainment unit, play may commence.Type: ApplicationFiled: November 15, 2007Publication date: May 21, 2009Applicant: ARACHNID INC.Inventors: John R.
