An agent activated non-metal antenna for an ultra-high frequency (UHF) wireless sensor having a radio frequency identification (RFID) tag in electronic communication with the non-metal antenna, and a wireless data communication integrated circuit (IC), includes a conductive stimuli-responsive hydrogel material configured to be inactive prior to an interaction with an activating agent and active upon the interaction with the activating agent. The antenna is further configured to transmit power to turn on the wireless data communication IC only when the non-metal antenna is active upon interaction with the activating agent.

A computer-based method to facilitate detecting wheel imbalance, a tire pressure problem, or excessive tread wear on tires of a moving vehicle is disclosed. The method includes collecting (e.g., from an accelerometer of a mobile personal computing device) data that represents vibration that results, at least in part, from the vehicle's motion, and determining, with a computer-based processor, whether the moving vehicle has wheel imbalance, a tire pressure problem, and/or excessive tire tread wear based at least in part on the vibration data produced by the accelerometer (and, possibly other data), where the mobile personal computing device and the accelerometer are moving with the vehicle when the data is being collected.

Systems and methods are provided for managing data proxies. The systems and methods enable a proxy management system to store and manage data proxies that digitally represent real-world objects equipped with sensors. The data proxy of an object is made up of data sampled by the object's sensors and data estimated using the sampled data. The sampling rate at which the data is sampled can be optimized such that it conforms with target quality of data (QoD) requirements and/or target data acquisition costs. The QoD requirements can be based on requirements set by each of the applications associated with an object. The proxy management system can use the sampled data and estimated data to (1) ensure that incoming messages, if executed, would not have negative consequences; and (2) monitor objects to determine if and when they are expected to approach undesirable states, or if they have already reached such undesirable states.

An apparatus for a clutchless manual transmission includes a transmission, a drive shaft, and a motor shaft. The transmission includes an input shaft, an output shaft, and an intermediate gear. The input shaft is coupled to an engine shaft to receive power and the output shaft is coupled to the drive shaft to transmit power to a wheel of a vehicle. The input shaft and output shaft are coupled by a plurality of input and output shaft gears. A first synchronizer is coupled to the output shaft to selectively engage a particular output shaft gear, adjusting the speed of the output shaft relative to the input shaft. The motor shaft receives power from a motor and includes a second synchronizer to selectively engage the engine shaft to the drive shaft via the motor shaft. The apparatus can be used to reduce acceleration and turbo lag in hybrid and high-performance vehicles.

Systems, devices, and methods for three-dimensional printing are provided. The systems, devices, and methods provide for high throughput printing by allowing for parallel extrusion within a single vertical layer of the printed object, i.e., parallel extrusion within an x-y coordinate plane. Any advancement of an extruder can be limited to movement along a single axis, or even no axis at all, so that printing occurs more quickly. In some embodiments, the extruder can include a printing plate that includes a plurality of apertures defined by conductive elements extending in a grid-like manner. The printer can be designed such that material is disposed to a build platform through the apertures only when the aperture is heated on all four sides, for instance by running current through the conductive elements that define the aperture. Other systems, devices, and methods for three-dimensional printing are also provided.

A system and method for providing predictive software upgrades is provided. Generally, the method comprising the steps of: querying a virtual vehicle application that simulates a real vehicle to determine one or more time period when the vehicle will be in an off state for long enough for updating of software to take place without the vehicle operating status being changed; transmitting a push notification to a user portable interactive communication device providing the one or more time periods determined, to the user for selection of one or more time period; receiving a selected one or more time period for upgrading of the software; transmitting a request for confirmation of a first of the one or more time period to the user portable interactive communication device at a predefined time period prior to the first of the one or more time period; and if the user confirms the first time period, instructing the upgrading of the vehicle control module by the vehicle at the first time period.

System and method for providing predictive software upgrades

A communication device for providing road conditions and monitoring congestion, contains a memory and a processor configured by the memory to perform the steps of: extracting key current vehicle and/or traffic insight; determining if the extracted key current vehicle and/or traffic insight represents a departure from expected vehicle and/or traffic insight; if the extracted key current vehicle and/or traffic insight is a departure from expected vehicle and/or traffic insight, using the key current vehicle and/or traffic insight to create a smart message, wherein the smart message contains the extracted key current vehicle and/or traffic insight; and if the extracted key current vehicle and/or traffic insight is a confirmation of expected vehicle and/or traffic insight, creating a confirmation message that does not contain the extracted key current vehicle and/or traffic insight, yet confirms similarity between the extracted key current vehicle and/or traffic insight and the expected vehicle and/or traffic insight.
