Wireless location using signal fingerprinting
InactiveUS20010022558A1Low costSpectrum efficiencyDirection finders using radio wavesBeacon systems using radio wavesInternet communicationCall tracing
A location system is disclosed for commercial wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location centers for outputting requested locations of commercially available handsets or mobile stations (MS) based on, e.g., CDMA, AMPS, NAMPS or TDMA communication standards, for processing both local MS location requests and more global MS location requests via, e.g., Internet communication between a distributed network of location centers. The system uses a plurality of MS locating technologies including those based on: (1) two-way TOA and TDOA; (2) pattern recognition; (3) distributed antenna provisioning; and (4) supplemental information from various types of very low cost non-infrastructure base stations for communicating via a typical commercial wireless base station infrastructure or a public telephone switching network. Accordingly, the traditional MS location difficulties, such as multipath, poor location accuracy and poor coverage are alleviated via such technologies in combination with strategies for: (a) automatically adapting and calibrating system performance according to environmental and geographical changes; (b) automatically capturing location signal data for continual enhancement of a self-maintaining historical data base retaining predictive location signal data; (c) evaluating MS locations according to both heuristics and constraints related to, e.g., terrain, MS velocity and MS path extrapolation from tracking and (d) adjusting likely MS locations adaptively and statistically so that the system becomes progressively more comprehensive and accurate. Further, the system can be modularly configured for use in location signaling environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. Accordingly, the system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

Three dimensional object pose estimation which employs dense depth information
InactiveUS7003134B1Accurate estimateImprove tracking performanceImage enhancementImage analysisGraphicsStructure from motion
Dense range data obtained at real-time rates is employed to estimate the pose of an articulated figure. In one approach, the range data is used in combination with a model of connected patches. Each patch is the planar convex hull of two circles, and a recursive procedure is carried out to determine an estimate of pose which most closely correlates to the range data. In another aspect of the invention, the dense range data is used in conjunction with image intensity information to improve pose tracking performance. The range information is used to determine the shape of an object, rather than assume a generic model or estimate structure from motion. In this aspect of the invention, a depth constraint equation, which is a counterpart to the classic brightness change constraint equation, is employed. Both constraints are used to jointly solve for motion estimates.

Method and system for identifying, matching and transacting information among portable devices within radio frequency proximity
InactiveUS20060166740A1Minimal processingReduce power consumptionVideo gamesSpecial data processing applicationsPagerDigital content
In today's increasingly populated, yet very busy world, there is a growing need to create community and enable an efficient flow of information through shared interactions; such as matching, alerting, gaming, and commerce. Interactions can be facilitated by advancing technology and the proliferation of wireless devices. Wireless devices and applications can facilitate the matching of people based on similar characteristics, token and data exchanges for gaming situations, or the sending of alerts to warn those entering hazardous areas. With the advent of inexpensive radio frequency (RF) chips and wireless communication standards of many forms, microprocessors (and computing ASICs), and flash memory embedded in many common devices, it is possible to increase the amount of automatic person to person interaction as people pass within RF range of the devices they carry with them or which may reside in fixed locations. The utility of the present invention will describe an application and system whereby current and future portable devices; such as mobile phones, personal digital assistants, pagers, AM / FM radios, music players, key fobs, watches, video playback devices, etc. will seamlessly interact to share information. The utility to the user is derived from systems' ability to match, alert, transact commerce and gaming within a system requiring little to no user intervention beyond the initial configuration. It is anticipated that with the technology described within the current invention: two people will be able to meet in a public setting as they pass each other because they have shared commonalities; individuals will be alerted to hazardous circumstances, perhaps a convicted sex offender in the area, construction zone, or approaching accident scene; groups of people will enjoy gaming opportunities by playing virtual tag with electronic tokens, until the winner is finally tagged; and users will be able to purchase digital content, such as songs, videos, or other streamed or broadcast media, by merely pressing a button on the receiving device. The utility of the current invention will further describe the application and systems which can be made available in a highly portable device or embedded into a host of commercially available devices.

High dynamic range brightness information is acquired by inputting detection current to a high (adjustable) gain resettable integrator whose output V(t) is compared to a Vth threshold by a comparator whose output is counted by a reset counter as V(t).gtoreq.Vth. When a desired count is attained, data acquisition ends, the counter is read, and the entire circuit is reset. A TOF data acquisition circuit includes first and second sequences of series-coupled delay units, and a like number of latch units coupled between respective delay units. A phase discriminator compares output from each chain and feedback a signal to one of the chains and to a comparator and can equalize delay through each chain. A control voltage is coupled to the remaining chain to affect through-propagation delay time. The latch units can capture the precise time when V(t).gtoreq.Vth.

Ventilator With Controlled Purge Function
InactiveUS20100051026A1Avoid clearingSpeed up the removal processRespiratorsInhalatorsEngineeringBreathing
This disclosure describes systems and methods for purging narrow diameter sensor tubing in a ventilation system. Among other aspects, this disclosure describes ventilation systems in which a sensor tube purge module utilizes a ventilator-generated signal to synchronize the purging of sensor tubes with the delivery of respiratory therapy. Through the signal, purging is prevented from occurring during inspiration and during events such as ventilation maneuvers. Purging may be further improved by monitoring the pressure of the gas used to purge the sensor tubes in order to prevent purges being performed when the pressure is too high or too low. One way to achieve this is by purging the sensor tubes using gas discharged from an accumulator, in which the pressure in the accumulator is monitored and controlled by the sensor tube purging module.

Atmospheric pressure, intermediate pressure and vacuum laser desorption ionization methods and ion sources are configured to increase ionization efficiency and the efficiency of transmitting ions to a mass to charge analyzer or ion mobility analyzer. An electric field is applied in the region of a sample target to accumulate ions generated from a local ion source on a solid or liquid phase sample prior to applying a laser desorption pulse. The electric field is changed just prior to or during the desorption laser pulse to promote the desorption of charged species and improve the ionization efficiency of desorbed sample species. After a delay, the electric field may be further changed to optimize focusing and transmission of ions into a mass spectrometer or ion mobility analyzer. Charged species may also be added to the region of the laser desorbed sample plume to promote ion-molecule reactions between the added ions and desorbed neutral sample species, increasing desorbed sample ionization efficiency and / or creating desired product ion species. The cycling of electric field changes is repeated in a timed sequence with one or more desorption laser pulse occurring per electric field change cycle. Embodiments of the invention comprise atmospheric pressure, intermediate pressure and vacuum pressure laser desorption ionization source methods and devices for increasing the analytical flexibility and improving the sensitivity of mass spectrometric analysis.
