    Abstract: A variable stiffness joint and method to alter the stiffness of the joint with multiple stiffness levels is described wherein a plurality of stiffness bits (m) are used for enabling 2 m stiffness level variations for the joint. Each stiffness bit comprises an elastic element in mechanical connection with a clutch (21, 22, 23). The joint revolves with zero stiffness level when all the clutches (21, 22, 23) are disengaged whereas a clutch (21, 22, 23) involves one of the elastic elements which alter the stiffness of the joint. Engaging other clutches (21, 22, 23) involve more elastic elements for altering the joint stiffness and the resultant joint stiffness is determined by adding the stiffness values of all the involved springs (6, 7, 8).

    Abstract: A method for transmitting a data block begins with segmenting the data block into a number of data sub-blocks. Each data sub-block where a number of high bits is greater than a number of low bits is then inverted. The data sub-blocks are then grouped into sets of data sub-blocks. For each set of data sub blocks, a number of pulses indicative of a number of high bits in each one of the data sub-blocks in the set is transmitted, there is a delay, and a number of pulses indicative of each high bit in each data sub-block of the set of data sub-blocks is transmitted followed by a delay. Finally, a number of pulses indicative of which ones of the data sub-blocks were inverted is transmitted.

    Abstract: Systems and methods for low-power single-wire communication are provided. In some embodiments, a method of operation of a transmitter to transmit a data word to a receiver using low-power single-wire communication includes receiving the data word to be transmitted to the receiver. The method also includes encoding the data word to be transmitted in a Pulsed Index Communication (PIC) format to produce a PIC data word and transmitting the PIC data word to the receiver. In this way, the transmitter may be able to transmit an increased amount of data while maintaining a simple communication protocol that uses low power and does not require a Clock-Data Recovery circuit.
