Abstract: A database stores a document as a plurality of encrypted records, where each record is indicative of an incremental change to the state of the document, and encrypted using a document key. The document key is stored with encryption decryptable using a group key, and the group key is stored with encryption decryptable using a first access key. In response to a request to rotate from the first access key to a second access key, the database decrypts the group key using the first access key, a stores a group key re-encrypted with the second access key.

Abstract: Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.

Abstract: Aspects of this disclosure relate to a front end architecture for selectively adding an external carrier aggregation band. A switch element can connect a radio frequency signal path to an antenna path through a frequency domain multiplexer, such as a diplexer, in a first mode. The switch element can connect the radio frequency path to the antenna path and bypass the frequency domain multiplexer in a second mode. The frequency domain multiplexer can be external to a front end module that include the radio frequency signal path. In the first mode, a front end system can support carrier aggregation with a band associated with circuitry implemented external to the front end module.

Abstract: An electronic messaging device includes a receiver configured to receive a message at one of a first operational frequency and second operational frequency. The messaging device can operate using a time synchronous protocol and can receive commands through over-the-internet-programming (OTIP) and over-the-air-programming (OTAP).

Abstract: The present systems, devices, and methods relate to managing shared vehicle access. Vehicle access can be provided to a candidate user based on whether the user is included in a list of at least one user associated with a respective virtual key. Virtual keys can be created, or lists of at least one user can be updated to include the candidate user, to in turn provide vehicle access. Virtual keys can be stored in a plurality of virtual key slots, with vehicle access being provided based on a virtual key stored in an active key slot. Status reports can be sent to a reservation management device, for updating virtual keys or lists of at least one user.

Abstract: Disclosed are recombinant insect ferritin nanoparticles that can be used to display two different trimeric antigens at an equal ratio. Also disclosed are nucleic acids encoding the recombinant insect ferritin nanoparticles and methods of producing the recombinant insect ferritin nanoparticles. Methods for eliciting an immune response in a subject are also provided.

Abstract: A photoionization sensor assembly includes a housing defining a chamber with a first end and an opposing second end and being permeable to the analyte gas and non-analyte gases. A radiation source is structured to emit photons into the chamber. A first, second and third electrode are positioned in the chamber. The photons ionize the analyte gas, are insufficient to ionize the non-analyte gases, and causing ejection of photoelectrons from the third electrode. A controller is structured to receive a measurement of a total pressure and electrically bias the electrodes to collect the photoelectrons on the first and second electrodes in a ratio dependent on the total pressure. The controller is structured to determine the ratio of photoelectrons that are collected on the first and second electrodes at the total pressure and determine an amount of electrical current due to ionization by correcting the measured current using the determined ratio.

Abstract: The present invention discloses a scissor jack comprising four arms hingedly arranged to provide two opposite elbows between a base and a load support. A pair of trunnions are provided with an outer trunnion at one outer elbow and a threaded trunnion at another outer elbow opposite to the one outer elbow connected through a threaded shaft. The inner third trunnion is connected to two rods to form a yoke. The yoke is configured to slideably pass through the outer trunnion of the one outer elbow to extend beyond the one outer elbow. A pair of levers are provided which are configured to be secured to the inner third trunnion. The scissor jack further comprises springs or any other retaining mechanism attached to a pair of levers, to ensure that the pair of levers return to their original location or position when the scissor jack is lowered.

Abstract: A plasma generation device for generating a plasma comprises a support having a first side and an opposing second side. The support is comprised of a ceramic matrix and a split-ring conductor is embedded in the ceramic matrix. A hermetically sealed via extends from the split-ring conductor to the second side of the support and connects to an electrical supply. A ground plane is formed on the second side of the support. A plasma is generated proximate to the first side of the support, and the support seals to a wall of the chamber such that the first side is exposed to the one or more gases inside the chamber and the second side is isolated from the plasma and the one or more gases inside of the chamber.

Abstract: A vegetative health mapping system which creates two- or three-dimensional maps and associates moisture content, soil density, ambient light, surface temperature, and/or additional indications of vegetative health with the map. Moisture content is inferred using radar return signals of near-field and/or far-field radar. By tuning various parameters of the one or more radar (e.g. frequency, focus, power), additional data may be associated with the map from subterranean features (such as rocks, soil density, sprinklers, etc.). Additional sensors (camera(s), lidar, IMU, GPS, etc.) may be fused with radar returns to generate maps having associated moisture content, surface temperature, ambient light levels, additional indications of vegetative health (as may be determined by machine learned algorithms), etc. Such vegetative health maps may be provided to a user who, in turn, may indicate additional areas for the vegetative health device to scan or otherwise used to recommend and/or perform treatments.

Abstract: Useful thermoplastic polymer powders are formed by a method comprising: cooling a foam comprised of a thermoplastic foam below the brittleness temperature of the thermoplastic polymer, wherein the foam has an average strut dimension of 10 to 500 micrometers, and comminuting the cooled foam to form a thermoplastic polymer powder. The method allows for the efficient grinding of the thermoplastic polymer having improved morphology and desirable characteristics such as dry flow without flow aids.

Abstract: Systems and techniques for detecting a difference in orientation between a lawn mower and a surface on which the mower is mowing, or between portions of such surface, based on one or more of sensor data or map data are discussed. The difference in orientation may then be used to control the lawn mower by, for example, raising a deck height or idling a blade speed, though other actuations are contemplated. In some examples, an amount the deck height is raised may be based on the difference in orientation. Based on a subsequent difference detected being at or below a threshold difference, the mower may return to previous operating conditions including, but not limited to, returning a blade speed to a previous blade speed and/or returning the deck height to a previous deck height, among other controls. Such techniques may prevent undercutting turf due to such differences.

Abstract: To utilize a shared vehicle, a user can request access to the vehicle, which results in the generation of a virtual key. The virtual key is provided to a plurality of different devices, such as a vehicle device at the vehicle, and a user device in the possession of the user. Access to the vehicle can be granted and maintained by verification of the virtual key against data from an identification device at the vehicle, or from the user device. In this way, multiple options for vehicle access are available to the user, which increases flexibility and user-friendliness.
