Abstract: A server, e.g., a client (105, 107, 109), receives a request for a digital signature to be applied to digital information, obtains a representation of the information, determines a designation of key pair(s) to be applied thereto; and transmits a request for the digital signature to a front end server (103a, 103b). The front end server determines one or more of whether the client is authentic and authorized, the user identifier is authentic, and the user identifier is permitted to make the request. If so, the front end server transmits a request to generate a digital signature to a back end server (101). The back end server determines one or more of whether the front end server is authentic and the designated key pair correspond to the requesting front end server. If so, the back end server generates the digital signature based on the information and the key pair(s).

Abstract: An apparatus (100) used by a plurality of devices to authenticate an accessory (120) is configured to operate with a device (110) of the plurality of devices. The accessory (120) applies an authentication algorithm to a key and a challenge (130) received from the device (110) and generates a response (132) thereto. A challenge and response memory (114) stores a subset of a set of challenges (232) and pre-computed responses (230). The enabling circuit transmits a challenge (130) to the accessory (120) and receives a received response (132) therefrom. The enabling circuit (112) also compares the received response (132) to the stored response (230) corresponding to the stored challenge (232) sent to the accessory (120).

Abstract: A method of coordinating events in a microprocessor-based electronic device having a sleep mode to reduce current drain includes a first step of determining a list of times to perform associated operating system events requiring a wake-up period for the device. A next step includes establishing a timing of fixed events wherein the electronic device enters a wake-up period to perform the fixed events. A next step includes delaying the time for an operating system event to coincide with a fixed event such that the electronic device utilizes one coincident wake-up period to perform both of the operating system event and the fixed event. This removes the current drain associated with entering and exited an additional sleep period.

Abstract: A microcontroller (100) with an expansion port (112) includes internal ROM (110) and EEPROM (109) and an external expansion port. The EEPROM internal to the microcontroller is programmable only when the CPU (102) is executing instructions within the internal ROM. Additionally, instructions associated with a secure operation stored in the internal ROM may not be accessed without first executing the beginning instruction of the secure operation. Attempts to begin execution of the secure operation at any point other than the legal entry address will cause the internal ROM (110) to be disabled.

Abstract: The robotic end-effector system comprises a mounting bracket assembly attached to a manipulator arm of a robot. A dual shaft motor is attached to the mounting bracket assembly. The motor has first and second rotatable output shafts. The first shaft is for mounting an encoder for providing position data. A mechanical drive mechanism is connected to the motor and to the mounting bracket assembly. The mechanical drive mechanism converts rotational motion of the second output shaft to translational motion. A passive compliance system is connected to the mechanical drive mechanism. A load sensor system is supported by the compliance system for providing force data. An end-effector end piece is connected to the load sensor system. A closed loop computer control system is in communication with the motor for processing the position data and the force data for providing micro positioning of the end-effector end piece and for providing an active system compliance, thereby achieving the desired end-effector function.

Abstract: A method of operating a high speed, error-free data transmission system in a noisy medium comprises compressing data determined to be compressible, forward error correcting the data and interleaving the data in a bit matrix memory to enhance the forward error correction. Digital information packets are formulated including a header bearing a packet number, the total packet byte count, any packet number resend request, the data byte count of the actual data and a CRC. The digital information packet is loaded onto a transmitter carousel having a fixed number of sectors. The receiver receives the data, requests resend of any packet (by number) that is defective, error corrects if necessary and sequentially loads the packet onto a receiver carousel. Packets or sequential packet groups are removed from the carousel, selectively decompressed and the data words extracted and sent to the output.
