  • Patent number: 9381106
    Abstract: A force distribution apparatus and method are presented. Various embodiments of the disclosed apparatus include a plurality of layers configured and oriented to be deployed on a subject in a manner that disperses forces and lowers peak pressures experienced by the subject when resting on a surface, which tends to minimize risks of deformation and local ischemia. An innovative combination of novel construction methods, material selections, and sensors produce an apparatus that possesses an inherent three-dimensional shape despite being built from essentially flat components, while also retaining an ability to effectively distribute forces and reduce pressures. Further embodiments of the disclosed apparatus are adapted to detect and monitor motion and position of the subject, providing retrospective or real-time data for caregivers.

  • Patent number: 9374369
    Abstract: Embodiments are directed to a system and method for authenticating a user of a client computer making a request to a server computer providing access to a network resource through an authentication platform that issues a challenge in response to the request requiring authentication of the user identity through a reply from the client computer, determining one or more items of context information related to at least one of the user, the request, and the client computer, and determining a disposition of the request based on the reply and the one or more items of context information. The reply includes a user password and may be provided by an authorizing client device.

  • Patent number: 8910493
    Abstract: A falling film plate type heat exchanger. The heat exchanger includes a pressure vessel surrounding an encapsulated stack of plates. Each plate has a primary fluid side and a secondary fluid side. The primary fluid will be a refrigerant—such as R-134a. The secondary fluid will typically be water. A film of refrigerant is applied to the primary fluid side of each plate, where it evaporates by absorbing heat from the secondary fluid on the other side of the plate. The invention uses embossed patterns on the plates to direct the flow of the primary and secondary fluids in a desired pattern. Further, the primary fluid side of each plate has a roughened surface treatment to increase the effective surface area and thereby increase the heat transfer rate.

  • Publication number: 20140128021
    Abstract: User activity on a mobile device is monitored and collected, and a resource usage model is constructed. The resource usage model describes a set of contexts in which the mobile device, and is the basis for determining a first exhaustion point for a resource. Based on the monitored activity, a prediction of a second exhaustion point for the resource time is made. If the second exhaustion point is prior to the first exhaustion point, usage of the resource is reduced.

  • Patent number: 8655307
    Abstract: Security is enhanced for a user of a mobile device by monitoring and controlling resource usage. Usage information associated with a mobile device is collected. The collected information is used to build a usage model for a user of the mobile device that describes a set of contexts in which the mobile device is used. User activity on the device is monitored and the model is consulted to determine a first time after which it will be acceptable for a battery of the mobile device to fall below a threshold charge level. Based on the monitored activity, a prediction of a second time is made for when the battery will fall below the threshold charge level. If the second time is before or a predetermined amount of time before the first time, usage of the battery is reduced, else, usage of the battery is not reduced.

  • Patent number: 7079009
    Abstract: Arbitration of multiple transponders, such as RFID tags, occurs in an interrogation field. The arbitration process is custom-tailored for individual applications, under software control, by the transponder reader or tag reader. Different wake-up slots are calculated for each tag during successive transmission cycles based upon the tag ID and the transmission cycle number. The tag reader may also send a special command to a tag to read its data and cause the tag to become decoupled from the environment. The tags may be selectively placed in either a tag-talk-first mode or a reader-talk-first mode. Furthermore, the tag reader may send a special fast read command to the tag which includes a read request and at least one parameter of the read request.

Different wake-up slots are calculated for each tag during successive transmission cycles based upon the tag ID and the transmission cycle number. The tag reader may send a special fast read command to the tag which includes a read request and communications control parameters including the number of time slots for transponder communications, the number of transmissions that an individual transponder is allowed to issue, and the data rate at which the reader communicates to the transponder. The tag reader may also send a special command to a tag to read its data and cause the tag to become decoupled from the environment.

  • Publication number: 20050147472
    Abstract: A process for treating neutralized waste solids from the processing of titanium-bearing ores, whereby the neutralized waste solids are contacted with an acid under conditions effective to dissolve at least some of the waste solids, and then residual undissolved solids are separated out prior to injection of the remainder into a subterranean waste disposal well. The process is particularly adapted to disposal of hazardous metal waste solids which have been deposited over time in a waste disposal pond but which are judged as posing a hazard for migration from the pond to surface and subterranean waters.
