  • Publication number: 20240129672
    Abstract: An actuator module includes a baseplate extending in a plane, a voice coil connected to the baseplate, and a magnet assembly. The actuator module also includes a rigid frame attached to the baseplate, the rigid frame comprising four stubs. The actuator module further includes a pair of springs suspending the magnet assembly relative to the frame and baseplate so that the voice coil extends into the air gap, the pair of springs including a first and second spring each shaped as a loop defining an aperture sized to accommodate motion of the magnet assembly along a direction of the coil axis, the first spring being attached to the frame at a first pair of the four stubs, the second spring being attached to the frame at a second pair of the four stubs, and both being attached to separate portions of the magnet assembly.

  • Patent number: 11962062
    Abstract: Phased array antennas, such as a multi-function aperture, are limited in performance and reliability by traditional air-cooled thermal management systems. A fuel-cooled multi-function aperture passes engine fuel through channels within the ribs of the multi-function aperture to provide better heat transfer than can be achieved through air cooled systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.

  • Publication number: 20240071593
    Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

  • Publication number: 20240073003
    Abstract: A method of data transfer from a tenant to a service provider comprises encrypting the data with a public key of a key pair generated by a secure device within the service provider system. The data thus cannot be accessed by the service provider during transmission. The data is generated with a corresponding access control list, which specifies that a valid certificate must be presented in order to grant a particular use of the data once stored. The tenant can thus retain control of the use of the data even though it has been transferred out of the tenant system. A method of controlling use of data securely stored in the service provider system comprises issuing a use certificate having an expiry time to the party requesting use of the data. The use certificate must be validated before use of the stored data is granted. This enables the tenant to grant use of the stored data for a limited time period.

  • Patent number: 11825014
    Abstract: A processor-implemented method includes receiving, at a first mobile compute device of a user, a service request. Curated service information associated with the service request is retrieved in response to the user input, and displayed via a graphical user interface (GUI) of the first mobile compute device. A user selection of a subset of the curated service information is received via the GUI, and a phone number is received in response to the user populating a phone number field of the GUI. A send icon is displayed via the GUI in response to receiving at least one of the selection or the phone number. In response to a user selecting the send icon, a communication with the subset of service information is sent to a second mobile compute device having the phone number and associated with a service recipient, without including any self-identifying information associated with the user.

  • Publication number: 20230145214
    Abstract: Systems and methods for providing opportunistic vehicle air brake system pressurization are disclosed. Vehicle air tanks used within an air brake system are pressurized during a time a battery charging status is satisfied. For example, such air tanks may be pressurized via an air compressor at a time during which the vehicle is electrically connected to a power source other than a battery of the vehicle. An example of such a power source may include an electrical charger, such as an electric vehicle charging station, or an electric generator during a regenerative braking event. The air tanks may also be pressurized by using a battery to energize the air compressor, based on the battery being charged above a predetermined threshold.
