Abstract: A secure device comprises a secure computing environment (SCE) that stores one or more cryptographic secrets, such as private keys, and is able to receive input from secure input devices such as a keypad or smartcard interface and provide output to secure output devices such as a secure display. The SCE provides safeguards against remote and physical exploits, erasing or rendering unusable the secrets in the event of actual or suspected exploit, protecting the secrets from compromise. The SCE may digitally sign internally generated messages or messages from an external device such as a smartphone. Message signing conditions may be checked and satisfied in the SCE before a digitally signed message is generated. Messages may be automatically signed if they satisfy specified conditions. The secure device may be used as part of a multisignature scheme in which a plurality of private keys are used to create a digital signature.

Abstract: A grasp-activated power switch is integrated within a handle for a hand-held power tool. The switch has an inner channel having an outer conductive layer, and a flexible outer shell having an inner conductive layer separated from the outer conductive layer by an air gap. On its surface the outer shell has actuating and non-actuating areas. A manual grasping force when applied to the actuating area flexes the inner conductive layer across the gap and electrically couples the two layers. The closure energizes an RF transmitter, which sends a pulse to a complementary receiver. With each pulse, the receiver toggles power to a motor off or on, and when on, the motor transmits power through the inner channel. When operating the tool, an operator may grasp the non-actuating area to avoid powering the tool off or on. The inner conductive layer may consist of conductive segments separated by a resilient insulator that maintains the switch open in the absence of a grasping force.

Abstract: A golf club head and golf club having a large volume, large head dimensions, and/or large face characteristics, as well as unique mass property attributes driven by relationships not often considered in conventional club head design, to achieve a resistance to squaring the club head during a golf swing that is comfortable to the novice golfer, stability during off-center impacts, and preferred launch characteristics. This is achieved in part via establishing a club head configuration and associated center of gravity location that results in a preferred magnitude of Delta1 and Delta2 values, CG angle, moments of inertia, and associated ratios, relationships, and club head mass property characteristics influenced by these variables, to account for the scale of the club head and achieve improved performance.

Abstract: This disclosure presents a method and process to improve the accuracy of the calculations for true vertical depth and Eastings and Northings pair of a borehole while drilling operations are in progress. The method utilizes continuous survey parameters that are collected while drilling operations are in progress, and that have been collected between two neighboring stationary survey parameters. The stationary survey parameters are assumed to be ground truth and are fused with an invertible solution to a low order polynomial to generate the true vertical depth and an Eastings and Northings pair at each continuous survey location. An objective function can be used to optimize and solve the polynomial. The method can be performed on a well site controller, a geo-steering system, a bottom hole assembly, or other computing system capable of receiving the collected measurements, performing the method steps, and communicating the resultant borehole position parameters to other systems.
