  • Patent number: 11935180
    Abstract: Examples of the disclosure describe systems and methods for presenting virtual content on a wearable head device. In some embodiments, a state of a wearable head device is determined by minimizing a total error based on a reduced weight associated with a reprojection error. A view reflecting the determined state of the wearable head device is presented via a display of the wearable head device. In some embodiments, a wearable head device calculates a preintegration term based on the image data received via a sensor of the wearable head device and the inertial data received via a first IMU and a second IMU of the wearable head device. The wearable head device estimates a position of the device based on the preintegration term, and the wearable head device presents the virtual content based on the position of the device.

  • Patent number: 11338285
    Abstract: A technique relates to a fluidic cell configured to hold a nanofluidic chip. A first plate is configured to hold the nanofluidic chip. A second plate is configured to fit on top of the first plate, such that the nanofluidic chip is held in place. The second plate has at least one first port and at least one second port. The second plate has an entrance hole configured to communicate with an inlet hole of the nanofluidic chip. The second port is angled above the first port, such that the first port and second port intersect to form a junction. The second port is formed to have a line-of-sight to the entrance hole, such that the second port is configured to receive input for extracting air trapped at a vicinity of the entrance hole.

  • Patent number: 10706153
    Abstract: An information handling system (IHS) may implement techniques to detect a power-on event, to determine whether an authorized cryptographic erase operation of a storage device that implements cryptographic erasure is pending and, during an initialization sequence, to send to the device in response to determining that no such operation is pending, a command to disable cryptographic erasure on the device. The command may set an indicator on the device that, when set, disables cryptographic erasure. In response to determining that an authorized cryptographic erase operation is pending, the IHS may refrain from sending the command to disable cryptographic erasure on the device, and may send a command to cause the pending operation to be performed. In response to receiving an indication of completion of the pending operation, the IHS may clear an indicator that an authorized cryptographic erase operation is pending and initiate a power-on or reboot event.
