Abstract: The disclosed computer-implemented method for multi-lane data bus inversion can include receiving data for transmission via a plurality of data lanes, each data lane corresponding to one of a plurality of inversion bits, and, for each data lane within the plurality of data lanes, applying the corresponding inversion bit to each bit within the data lane. Various other methods, apparatuses, and systems are also disclosed.

Abstract: A power distribution controller for a hybrid aircraft is configured to continuously: obtain a state-of-charge (SoC) measurement for a battery of the hybrid aircraft; obtain a fuel level measurement for a secondary energy source of the hybrid aircraft; receive a control input indicating one of a throttle level or an operating mode for one or more motors of the hybrid aircraft; calculate a ratio of energy to source from each of the battery and the secondary energy source in order to operate the one or more motors of the hybrid aircraft based on the control input, the SoC measurement, and the fuel level measurement; and transmit a control signal that causes energy to be apportioned from the battery and the secondary energy source to the one or more motors based on the determined ratio.

Abstract: A protective case for a mobile electronic communication device includes a rear cover including a compressible member and a catch, the compressible member and the catch being spaced from each other to form an alcove; and a front cover including a rim configured to extend into the alcove, the rim having an inner surface configured to contact the compressible member and an outer surface opposite the inner surface configured to engage the catch.

Abstract: An activation device for a patient alarm system. The activation device comprises a resiliently deformable bladder defining an internal volume and a pressure switch in fluid communication with the internal volume and connected to an alarm system. Squeezing the resiliently deformable bladder operates the pressure switch, which activates the alarm system.

Abstract: An automatic record player in which the mechanism for pivoting the pick-up arm inwardly and outwardly relative to the turntable includes a first reciprocatably rotatable member and a second similar member releasably connectable to the first member to be driven thereby and releasably connectable to the pick-up arm vertical spindle to drive the pick-up arm inwardly relative to the turntable, the first member being releasably connectable to the pick-up arm vertical spindle to drive the pick-up arm outwardly relative to the turntable.
