Abstract: A cross authentication method includes steps of: a host central processing unit (CPU) module sending to a baseboard management controller (BIC) a request for BMC signature; the host CPU module receiving BMC signature data from the BMC; the host CPU module determining whether the received BMC signature data is authentic based on a BMC public key stored in the host CPU module; and the host CPU module allowing the BMC to access the host CPU module when it is determined that the BMC signature data is authentic.

Abstract: In a general aspect, a circuit can include a reference current generator configured to generate a first current signal representative of a threshold voltage. The circuit can also include a current comparator configured to mirror the first current signal, generate a second current signal representative of a received voltage and compare the second current signal to the first current signal. The current comparator can also be configured to provide a detection signal at a first logic value to indicate that the received voltage is below the threshold voltage when the comparison of the second current signal with the first current signal indicates that the received voltage is less than the threshold voltage.

Abstract: Systems (100, 900, 1100), devices, and methods may be used to print or use a patient-specific waterjet cut guide (104, 302, 902, 1102). A method may include receiving, at a processor, image data of a bone (102, 308) of a patient (702), rendering a model of the bone (102, 308) (704) and generating a cut guide model using the model of the bone (102, 308) (706). The method may include printing, using a three-dimensional (3D) printer, a waterjet cut guide (104, 302, 902, 1102) using the cut guide model. A method may include using the patient-specific waterjet cut guide (104, 302, 902, 1102) to perform a resection using a waterjet cutting device, the waterjet cutting device including a nozzle (108, 306, 406, 500A, 500B) insertable into a cut guide slot (106B, 304, 310, 906, 1104) of the patient-specific waterjet cut guide (104, 302, 902, 1102).

Abstract: Methods, systems, and configured storage media are provided for discovering software updates, discovering if a given computer can use the software update, and then updating the computers with the software as needed automatically across a network without storing the updates on an intermediate machine within the network. Furthermore, when a failure is detected, the rollout is stopped and the software can be automatically removed from those computers that already were updated. The software update can be stored originally at an address that is inaccessible through the network firewall by intermediately uploading the software update to an update computer which is not a part of the network but has access through the firewall, which is then used to distribute the update.
