  • Publication number: 20250253046
    Abstract: Disclosed herein are mass spectrometry methods for determining glycoproteoform-based biomarkers. The methods comprise identifying, with a processor from mass spectrometry data of the glycoprotein, a set of glycoproteoforms where each of the glycoproteoforms have a measurable intact mass; generating, with the processor from the identified set of glycoproteoforms, a glycoproteoform network separated by saccharide features, determining, with the processor from the glycoproteoform network, a site-independent prediction of N-glycans mapped to biosynthesis pathways; and generating, with the processor from the determined N-glycans mapped to biosynthesis pathways, a glycan structure. The methods may be used to analyze a glycoprotein in a subject, analyze disease progression, or identify disease onset or a recovery.

  • Patent number: 12357204
    Abstract: An oximetry device includes an inductive detector. When the oximetry device is sealed in a sheath and a latch of the sheath is in a latched position, the inductive detector inductively detects that latch. The oximeter device uses first information received from the detector for the latch being in the latched position to allow the device to take oximetry measurements. The oximeter device uses second information received from the detector for the latch not being in the latched position to allow the device to display a message on a display of the device that the sheath is not sealed. The displayed message indicates to a user that the sheath lid needs to be closed. The closed lid prevents contaminants in the sheath from reaching patient tissue during use of the device and sheath.

  • Patent number: 12284159
    Abstract: A router node comprises a link discovery module, a security module, a secure access module and storage. The link discovery module discovers a link to an adjacent router node and receives its first loopback address. The link discovery module creates a first tunnel between the security module in the router node and the first loopback address. The security module receives a second loopback address for the second router node, and creates a second tunnel. The security module repeats the discovering, receiving and creating steps for each router node adjacent to the first router node. The storage separately stores a link discovery routing table which comprises information relating to the links between the router node and each adjacent router note; a security routing table which stores the unique first loopback address; and a secure access routing table which stores the unique second loopback address.

  • Patent number: 12254136
    Abstract: Broadly speaking, embodiments of the present techniques provide haptic button assemblies in which the haptic button has a low profile while still providing a satisfying tactile response or sensation to a user. Advantageously, the haptic button assemblies may have a profile that, for example, enables the assembly to be incorporated into the free space along an edge of a portable computing device. The haptic assemblies may, for example, be arranged to move the button perpendicularly with respect to the edge of the device.

  • Patent number: 12228113
    Abstract: An SMA actuator assembly (1a) for driving or rotating a movable part (20) in a predetermined direction or sense by a plurality of repeated incremental steps is provided. The SMA actuator assembly comprises the movable part; a first engagement portion (31) for engaging the movable part; two SMA wires (41, 42) arranged to move the first engagement portion such that the first engagement portion repeatedly, for each of said incremental steps, is configured to do the following: engage with the movable part from a starting position, exert a force or torque on the movable part in the predetermined direction and disengage from the movable part and return to the starting position. The exertion of the force or torque on the movable part and the engaging or disengaging with the movable part are caused by contraction or relaxation of the two SMA wires.
