Abstract: A system and method for optimizing drilling with a rotary steerable system may monitor downhole signals associated with vibrational loads along a drill string during drilling. A downhole controller at a rotary steerable bottom-hole adapter may generate a control indication for modifying drilling parameters of a drill bit in response to detecting harmful vibrational loads for the drill string. A modification of the drilling speed and direction of the drill bit used for drilling may be performed based on the control indication.

Abstract: A set of hardware security modules (HSMs) in a database system may implement a key management system with a database storing encryption keys or other secrets. The set of HSMs may identify a first key encryption key (KEK) and a second KEK stored in the set of HSMs. The set of HSMs may retrieve, from the database, a set of encryption keys encrypted by the first KEK and decrypt each encryption key of the set of encryption keys using the first KEK. The set of HSMs may re-encrypt each encryption key of the set of encryption keys with the second KEK and transmit, to the database, the set of encrypted encryption keys encrypted by the second KEK for storage. Then, the set of HSMs may delete the first KEK from the set of HSMs.

Abstract: Methods, systems, and devices for transparent data encryption are described. A transparent proxy may enforce a specific encryption policy for a data transmission from a source host to a target host, where the transparent proxy determines if the data transmission is encrypted according to a specific encryption policy prior to forwarding the data transmission to the target host. As such, if the data transmission is not encrypted according to the specific encryption policy, the transparent proxy may encrypt the data transmission and then forward it to the target host. Alternatively, if the transparent proxy determines that the data transmission is encrypted according to the specific encryption policy, then the transparent proxy may refrain from further encrypting the data transmission and forward the data transmission to the target host without the additional encryption.

Abstract: Devices, systems, and/or methods for immobilizing a patient's head and simultaneously providing emergency respiration for the patient includes, in some embodiments, a head immobilizer, a bag valve mask (BVM), an endotracheal tube (ET) bracket, and/or an oxygen face mask. In some embodiments where head immobilization is not needed, a cardiopulmonary resuscitation (CPR) board may be used in lieu of the head immobilizer. Each such embodiment is configured to require reduced manual intervention by a caregiver without reducing the effectiveness of each medical device and/or system. An adjustable BVM holder integrated into the head immobilizer secures the BVM on the patient. In embodiments with a BVM, only a single hand is necessary to provide emergency respiration, freeing the caregiver's other hand for other caregiving tasks. Such a head immobilizer may secure an ET bracket and/or face mask to a patient, allowing for hands-free operation during patient treatment, movement, and transportation.

Abstract: A stump grinder has a grinding arm that durably mounts a rotatable grinding wheel by securing the drive shaft of a motor to the grinding wheel such that a pair of bearings within the motor support one side of the grinding wheel and by supporting the other side of the grinding wheel with a stub shaft received within a third bearing. The grinding arm is laterally offset on the frame of the stump grinder to have a swing angle that is not symmetrical relative to the width of the frame, but with the swing angle starting at one side of the frame and then traversing across substantially the entire width of the frame to improve the ability of the operator to see the grinding wheel. A single joystick is movable in orthogonal directions corresponding to desired up and down and side-to-side pivoting motions of the grinding arm. The joystick includes a depressible trigger for starting and stopping the operation of the grinding wheel.
