20100259406 | System and method for measuring fluid pressure - A battery/self powered electronic pressure gauge having electronic measurement, control, output, and display capability is described having the flexibility of using a sampling rate that is variable, based on either a random sampling scheme or one that learns from the history of use during the previous minutes, hours, days, months, etc. The variable sampling rate enables extended operational time before replacement of the battery. The pressure gauge can be configured to sense “intent” to change pressure in the outlet line and to revise its sampling protocol. This “intent” can be defined by the detection of the proximity of a user's hand to the pressure regulator. | 10-14-2010 |
20120245865 | SYSTEM AND METHOD FOR MEASURING FLUID PRESSURE - A method of reducing power consumption in a pressure (vacuum) regulator system by waking the regulator upon detection of a change in pressure beyond a set band, including: defining a sampling time-window to sample a pressure in the pressure regulator system; generating a random number of pressure samples within the defined sampling time-window; acquiring data of the randomly generated number of pressure samples within the defined sampling time-window; adjusting the defined sampling time-window in response to a change in pressure beyond a set band; and transmitting the data to an output device. | 09-27-2012 |
20130069783 | SYSTEM AND METHOD FOR MEASURING FLUID PRESSURE - A method of reducing power consumption in a pressure (vacuum) regulator system by waking the regulator upon detection of a person's hand proximity prior to adjustment of a pressure controller, including: defining a sampling time-window to sample a pressure in the pressure regulator system; generating a random number of pressure samples within the defined sampling time-window; acquiring data of the randomly generated number of pressure samples within the defined sampling time-window; adjusting the defined sampling time-window in response to a triggering of a proximity sensor; and wirelessly transmitting the data to an output device. | 03-21-2013 |
20130267919 | SOLENOID ACTIVATED VACUUM CONTROL DEVICE - The invention herein applies generally to General-purpose, Surgical and Tracheal suction regulators. In one embodiment of the invention, at least one micro-latching valve is opened and closed by at least one solenoid electromechanical actuator. The micro-latching solenoid valve in turns opens and closes at least one main valve that is connected the hospital vacuum or gas intake conduit. The latching nature of the solenoid, along with its low power activation allows for a battery powered, long-life device. Timing and control of the electromechanical actuator is performed by a low power micro-controller. This provides opportunity for highly accurate timing cycles, user adjustable timing intervals and feedback loop control operations. The invention also features a wireless suction control system of many suction regulators comprising a network. Wherein the plurality of wireless suction regulators are linked to at least one router with at least one wireless transmitter, and the network is linked through the router to the internet. | 10-10-2013 |

20090209896 | Method and apparatus for time-dependent and temperature-dependent clinical alert - Devices and methods are disclosed for measuring a pre-defined period as a method to alert medical personnel of the need for clinical intervention. Many invasive and non-invasive medical procedures require constant monitoring or intervention. Failure to properly observe or intervene may result in clinical harm. The devices and methods disclosed herein are useful in any field of medicine where periodic monitoring or procedures are required. The devices is designed to be familiar to medical personnel, and in its most common form will be packaged as a band aid, but may also be packaged as a coin sized device that adheres to or clips onto a patient's bandage, limb, or on a necklace. The timer provides an audible warning of timeout, a visual indication of timeout, a tactile indication or any combination of the three. The number of hours in the countdown sequence is variable and determined from a series of choices provided to the caregiver. The device can be used to monitor temperature and warn of an infection. | 08-20-2009 |
20090231159 | Sequenced vehicular traffic guiding system - A system of signal emitting modules is disclosed. The modules emit light or other signals to warn oncoming traffic that a road or other pathway has changed or is traversing a tortuous pathway. The modules are interconnected in a sequence so that they flash on and off in a pattern that leads the driver or observer along a path with less confusion than with randomly flashing or steady lights or reflectors. The modules are self-powered and can be arrayed first and programmed following deployment. The programming can be done with “mesh” technology, an external controller, or by dialing a specific number in each of a plurality of distributed controllers. The modules can improve highway safety by reducing driver confusion. The modules are arrayed to prevent a driver from seeing them from an oncoming direction. The driver coming from the opposite direction will have his or her own guiding system. The modules can also be deployed for use in nautical situations, to designate nautical obstructions (such as entering a harbor), shallow water, or other area of danger, and in the field of aviation to mark the direction and position of temporary runways or landing zones for both fixed wing and rotary wing aircraft. | 09-17-2009 |
20110071482 | DEVICES AND METHODS FOR SIGNALING WHEN ACTION IS DUE IN RELATION TO A MEDICAL DEVICE - Methods and devices for signaling to a subject or subject's care giver the occurrence of at least one event selected from: a) expiration or impending expiration of a predetermined time period and/or b) a change in a physiological or device-associated variable, associated with a medical device that is positioned on, in or connected to the subject's body. | 03-24-2011 |
20120256765 | SEQUENCED VEHICULAR TRAFFIC GUIDING SYSTEM - A system for marking a route, path or boundary. The system may comprise a plurality of modules, each of which comprises a signaling device, a radiofrequency apparatus and control circuitry. Such modules are positionable in an array which marks the route, path or boundary. When positioned in the array, the modules undergo radiofrequency communication with one another and the control circuitry causes the signaling devices of the modules to emit warning signals in sequence from a first-positioned module of the array to a last-positioned module of the array. | 10-11-2012 |
20130271294 | SEQUENCED GUIDING SYSTEMS WITH LOCATION DESIGNATION CAPABILITY - Systems and methods for marking a route, path or boundary. Signaling modules are positioned in an array to mark the route, path or boundary. The modules undergo radiofrequency communication with one another and emit signals in sequence from a first-positioned module of the array to a last-positioned module of the array. A selected one or more of the modules is/are programmed or adapted to emit a signal that is distinguishable from the signals emitted by the other modules. | 10-17-2013 |
20130293396 | SEQUENCED GUIDING SYSTEMS FOR VEHICLES AND PEDESTRIANS - Devices, systems and methods wherein sequential signals are emitted from a plurality of signaling modules positioned in an array which demarcates a route or boundaries to be followed by a pedestrian or vehicle. | 11-07-2013 |
