  • Patent number: 12251535
    Abstract: A fluid delivery system includes a fluid pump and a fluid management system. The fluid management system receives input indicating a fluid (such as including a drug, a therapy, etc.) of a particular type to be delivered to a recipient. The fluid management system maps the particular type of the fluid to a set of patient parameters to be monitored during the delivery of the fluid to the recipient. During the delivery of the fluid to the recipient, the fluid management system monitors feedback from the recipient for each of the patient parameters in the set. Based on the feedback, the fluid management system controls the delivery of the fluid to the recipient.

  • Patent number: 12092822
    Abstract: Systems and methods for switching between data connections establishing between an augmented reality display unit and a peripheral device. The systems and methods can automatically switch between communication modules, antennas, or frequencies based on sensor data to reduce or eliminate the effects of proximity to or submersion beneath water. In some examples, switching between communication modules, antennas, or frequencies is based on motion of the user's head or the electrical resistance, salinity, or chemical composition of a body of water the augmented reality display unit is placed within.

  • Patent number: 12010143
    Abstract: Establishing a transfer mode between devices for large bulk records over a TLS protocol by fragmenting an encrypted bulk record into a set of pre-defined block sizes for convenient transfer. The pre-defined block sizes are specifically sized to indicate a beginning and an end of the transfer of the associated blocks making up the large bulk record. A middle box is unaware of the association between the blocks and permits transfer according to the maximum transmission unit of the transport layer security (TLS) protocol. The fragmented bulk record is reconstructed and decrypted for use after the transfer.

  • Patent number: 11985239
    Abstract: Transport Layer Security (TLS) connection establishment between a client and a server for a new session is enabled using an ephemeral (temporary) key pair. In response to a request, the server generates a temporary certificate by signing an ephemeral public key using the server's private key. A certificate chain comprising at least the temporary certificate that includes the ephemeral public key, together with a server certificate, is output to the client by the server, which acts as a subordinate Certificate Authority. The client validates the certificates, generates a session key and outputs the session key wrapped by the ephemeral public key. To complete the connection establishment, the server applies the ephemeral private key to recover the session key derived at the client for the new session. The client and server thereafter use the session key to encrypt and decrypt data over the link. The ephemeral key pair is not reused.

  • Patent number: 11904739
    Abstract: A disc recliner mechanism for use in an automotive vehicle includes a plurality of pawls and a cam mounted between a guide plate and a tooth plate. Rotation of the cam moves the pawls between an extended position in which the pawls engage the tooth plate to lock the disc recliner mechanism and a retracted position in which the pawls disengage the tooth plate to unlock the disc recliner mechanism and allow rotation between the guide plate and the tooth plate. A notch is disposed on an engagement surface of a cam lobe disposed on the cam for reducing friction when the cam lobe engages a cam follower disposed on the pawls. The tooth plate includes a circumferential outer lip with a concentric channel for retaining lubricant and reducing rotational friction between the tooth plate and the guide plate.

  • Patent number: 11892938
    Abstract: An analyzer system inputs parameter values from trace files of a software application into an autoencoder. The analyzer system adjusts weights of the edges between nodes in the autoencoder until reconstruction errors in outputs are minimized. The analyzer system receives a selection of a parameter represented in an autoencoder. In response, the analyzer system identifies hidden layer nodes connected to an output node corresponding to the selected parameter and identifies other output nodes connected to the hidden layer nodes. The analyzer system retrieves weights assigned to edges between the hidden layer nodes and the other output nodes. The analyzer system calculates correlation values between the output node corresponding to the selected parameter and each of the other output nodes and outputs the correlation values. A user can use the correlation values to better direct the root cause analysis.

  • Patent number: 11857755
    Abstract: Via communications with an association management resource, an operator of a respective fluid delivery system can associate a medical device (fluid pump) with a particular entity such as a patient, location, one or more other medical devices, the caregiver, etc. Thereafter, the operator of the fluid delivery system is able to better manage use of the fluid delivery system based on relevant medical information, which is accessible as a result of creating the association. For example, the association management resource gathers and stores information associated with the entity prior to the operator providing the input associating the fluid delivery system with the entity. After the operator of the fluid delivery system creates the association, the medical information associated with the entity is immediately available to the fluid delivery system and/or corresponding operator of the fluid delivery system.

  • Patent number: 11847868
    Abstract: A system and method for monitoring vehicle performance and updating engine control parameters, which provides a solution to the problem of tuning engine control parameters for a vehicle. The core components of the invention are an engine controller coupled to an interface device which communicates with a remote device. Generally speaking, the components are configured as follows: the engine controller receives signals from various sensors in a vehicle and the engine controller controls the engine based on engine control parameters and the signals from the sensors. The interface device monitors the engine control and sensor signals and transmits information to the remote device. The remote device receives the information and sends back updated engine control parameters. The interface device receives the updated engine control parameters and communicates with the engine controller to update the engine control parameters using the updated engine control parameters.

  • Publication number: 20230341682
    Abstract: An imaging apparatus for stereoscopic viewing has a frame that seats against the head of a viewer. A left-eye imaging apparatus and a right-eye imaging apparatus are supported by the frame. The frame is reshapeable in a manner that changes a relative alignment of the left-eye imaging apparatus and the right-eye imaging apparatus to accommodate different viewer head anatomies. An adjustment mechanism responsive to the reshaping of the frame restores relative alignment of the left-eye imaging apparatus and the right-eye imaging apparatus for conveying stereoscopic virtual images to the viewer.
