Abstract: A system for use in wirelessly monitoring a pipeline such as a natural gas pipe. The system includes a locator configured to wirelessly transmit power and a subsoil sensor marker located adjacent the pipe and configured to wirelessly communicate with the locator. The sensor marker includes a microcontroller, a memory module, a sensor configured to sense the presence of a gas, and a power module. The power module is configured to harvest a sufficient amount of the power wirelessly transmitted from the locator in order to operate the microcontroller to take a measurement via the sensor, save the measurement in the memory module, and wirelessly transmit the measurement to the locator.

Abstract: A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film 200. The first element of the multilayer polymer optical film is a core layer 202 that is made up of a multilayer optical stack. The multilayer optical stack of core layer 202 includes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer 204 (for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layer 204 may include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical film 200 may optionally also include an adhesive layer 208 that is positioned between the core layer 202 and a surface onto which the multilayer polymer optical film is to be adhered.

Abstract: A presentation request and delivery system includes a client device and a presentation system. In some cases, the client device is configured to send a request for at least part of the presentation being presented on the presentation system, where the request includes an audience identification. In some other cases, the client device is configured to obtain a device identification of a presentation device via a line-of-sight communication interface and send a request for at least part of the presentation, where the request may include an audience identification and at least part of the device identification. Upon receiving the request, the presentation system will verify whether the request is authorized using the audience identification and deliver the at least part of the presentation requested if the request is authorized.

Abstract: A heads-up display system includes a polarizing beam splitter, a fold mirror, a heads-up display mirror, and a picture generating unit configured to emit a picture light. The polarizing beam splitter, the fold mirror, and the heads-up display mirror define a cavity, and the picture generating unit is disposed outside the cavity. The picture light emitted from the picture-generating unit enters the cavity after being transmitted by the polarizing beam splitter a first time, and the picture light exits the cavity after being transmitted by the polarizing beam splitter a second time.

Abstract: Methods for management of a powertrain system in a vehicle. The methods receive data or signals from multiple sensors associated with the vehicle. Optimum thresholds for classifications of the sensor data can be changed based injecting signals into the powertrain system and receiving responsive signals. Expected priorities for the sensor signals can be altered based upon attributes of the signals and confirming actual priorities for the signals. Look-up tables for engine management can be modified based upon injecting signals into the powertrain system and measuring a utility of the responsive signals. The methods can thus dynamically alter and modify data for powertrain management, such as look-up tables, during vehicle operation under a wide range of conditions.
