Abstract: A neural stimulus comprises at least three stimulus components, each comprising at least one of a temporal stimulus phase and a spatial stimulus pole. A first stimulus component delivers a first charge which is unequal to a third charge delivered by a third stimulus component, and the first charge and third charge are selected so as to give rise to reduced artefact at recording electrodes. In turn this may be exploited to independently control a correlation delay of a vector detector and an artefact vector to be non-parallel or orthogonal.

The cable sleeve has a braking system that includes a constant-contact wheel, a rotor that is connected to the constant-contact wheel, a cam plate, and a braking shoe.

Abstract: Supporting suppression of distortion caused by a power amplifier, “PA”, included in a transmitter system configured to perform digital predistortion, “DPD”, and feedforward, “FF”, linearization on multiple digital input signals relating to different frequency bands, respectively. The PA is used for power amplification in preparation for transmission by a wireless communication network and is operative with an instantaneous bandwidth, “IBW’”. Information is obtained identifying one or more intermodulation, “IM”, components outside the frequency bands but within the IBW, and caused by said PA. The identified IM components are selectively processed as part of said DPD to thereby suppress formation of at least some of the identified IM components, and/or as part of the FF linearization by adding reference signals to the FF linearization, which reference signals correspond to at least some of the identified IM components.

Abstract: A patient monitoring hub can communicate bidirectionally with external devices such as a board-in-cable or a dongle. Medical data can be communicated from the patient monitoring hub to the external devices to cause the external devices to initiate actions. For example, an external device can perform calculations based on data received from the patient monitoring hub, or take other actions (for example, creating a new patient profile, resetting baseline values for algorithms, calibrating algorithms, etc.). The external device can also communicate display characteristics associated with its data to the monitoring hub. The monitoring hub can calculate a set of options for combined layouts corresponding to different external devices or parameters. A display option may be selected for arranging a display screen estate on the monitoring hub.

Abstract: An implantable device for controlling electrical conditions of body tissue. A feedback sense electrode and a compensation electrode are positioned proximal to the tissue to make electrical contact with the tissue.
