Patent number: 7130664Abstract: The present invention provides a remote notification device in electronic communication with a user's personal communication device that alerts the user that the personal communication device is receiving an incoming telecommunications signal. A user who is not in operable contact with the communication device is alerted to the incoming call, message, or page by the remote notification device, which is in operable contact with the user, and alerts the user with a suitable indication (e.g., visual, audible, and/or tactile). The remote notification device preferably permits the user to not alter his or her desired appearance in social situations. The remote notification device is easily concealable or integral to an article of clothing, piece of jewelry, piercing, or accessory that the user desires to wear or carry independent of the desire to be notified of incoming calls, messages, or pages.Type: GrantFiled: June 12, 2003Date of Patent: October 31, 2006Inventor: Daniel P. Williams

Patent number: 7106180Abstract: An acoustic warning or alerting system for directing an audible warning signal to at least one intended recipient, while reducing the chance that the warning signal will be heard by others within the proximity of the system. The system includes a modulator for modulating an ultrasonic carrier signal with a processed audio signal, a driver amplifier for amplifying the modulated carrier signal, and a parametric array of acoustic transducers for projecting the modulated and amplified carrier signal through a propagation medium for subsequent regeneration of the audio signal along a pre-selected projection path. The parametric array of audio transducers operates by employing the nonlinear interaction between high frequency sound components and the propagation medium to generate at least one highly directional beam of lower frequency sounds within the propagation medium.Type: GrantFiled: August 30, 2002Date of Patent: September 12, 2006Inventor: Frank Joseph Pompei

Patent number: 7098778Abstract: An Impact sensor assembly provides a modular housing for vehicle impact sensors. The assembly comprises an impact sensor, an upper housing member, a lower housing member and a connector for establishing an electrical connection between the assembly and an appropriate vehicle system. The assembly may further include electronics for processing signals received from the sensor. The lower housing member receives and retains the sensor, and closeably interacts with the upper housing member to encase the sensor. The assembly defines structural features that ensures its proper installation into a vehicle. The preferred embodiment assures proper functioning of deformation impact sensors. A method of installing the assembly provides a process for rapid and proper installation of the assembly into a vehicle.Type: GrantFiled: September 27, 2000Date of Patent: August 29, 2006Assignee: Autoliv ASP, Inc.Inventors: Paul K. Zoratti, Jeffrey A. Bochenek

Patent number: 7071816Abstract: An audible alert device includes a pulse width modulated signal generator. The audible alert device and method for manufacturing the audible alert device also provides resonant frequency and decibel peaking capabilities. Resonant frequency and decibel peaking routines may conducted at the time of manufacture, upon startup of the alarm or during operation of the alarm. The audible alert device may be programmed during a manufacturing step to exhibit a selected operation mode so that one circuit may be manufactured and programmed to operate in any of a number of operation modes or device configurations. A programming station allows an audible alert device to be programmed during a manufacturing step to exhibit a selected operation mode. Programming may occur by connection of the audible alert device to the programming device by one or more audible alert device power conductors.Type: GrantFiled: March 1, 2004Date of Patent: July 4, 2006Assignee: Electronic Controls CompanyInventors: Tony J. Tewell, Tracy C. Lowder, James E. Barber

Patent number: 7049959Abstract: The present invention provides a non-power source type monitor device installed in a place where a non-power source system needs to be used or a place preferably suitable for the non-power source system, in which a quantity generated energy not lower than several ten times as much as an output of electric current obtained by usual piezoelectric power generating device using steel balls can be assuredly obtained by striking a piezoelectric ceramics element once. A piezoelectric power generating device is formed commonly with capable of automatically repeatedly striking the piezoelectric ceramics element so that a quantity of generated energy of a practical level can be assuredly ensured as a power source of such type monitor device.Type: GrantFiled: February 24, 2004Date of Patent: May 23, 2006Assignee: USC CorporationInventor: Yasuhiro Sakai

Patent number: 7019621Abstract: A piezoelectric transducer comprises a piezoelectric component, an acoustic member attached to one of the surfaces of the piezoelectric component and a dampening material of low elastic modulus attached to one or both surfaces of the piezoelectric transducer. The piezoelectric component may comprise either an unimorph or a bimorph structure including a piezoceramic wafer made of lead zirconate titanate and a layer of dampening material sandwiched between the piezoelectric component and the acoustic member. The acoustic member comprises a surrounding wall portion and an end portion which form an acoustic chamber when the member is mounted on a surface of the piezoelectrie component. The end portion has an orifice to form a passageway from the chamber through the end portion to the outside of the member.Type: GrantFiled: January 2, 2001Date of Patent: March 28, 2006Inventors: Stanley E. Woodard, Robert L. Fox, Robert G. Bryant

Patent number: 6995659Abstract: A sound transducer comprises at least one sound unit based on at least one radially sound emitting diaphragm arranged in a substantially cylindrical or tubular form, the diaphragm including electromechanically converting material capable of creating sound by changing its physical state upon electrical excitation. In a single sound unit the diaphragm is arranged to be supported between an inner sound guiding sleeve and an outer sound guiding sleeve in order to form at least one axial acoustic channel between the diaphragm and at least one of the sleeves. At least at the exit side of the acoustic channel the axial ends of the diaphragm and the corresponding sound guiding sleeve are arranged to have mutual non-alignment in the plane perpendicular to the axis of the sound unit in order to reduce the acoustic mass that the acoustic channel represents. The invention further relates to a device with such a transducer.Type: GrantFiled: October 31, 2003Date of Patent: February 7, 2006Assignee: Nokia CorporationInventor: Alberto Soto-Nicolas
