Abstract: A physiological activity detection system comprises a signal acquisition module configured for non-invasively acquiring a signal from an anatomical structure of a user, the acquired signal having a physiological-encoded component and a periodic artifact component that dominates the physiological-encoded component. The physiological activity detection system further comprises a phase-locked loop (PLL) component configured for estimating a phase of the periodic artifact component of the acquired signal, and generating a periodic reference signal having a phase representative of the estimated phase of the periodic artifact component of the acquired signal.

Abstract: A lock configured to be operated by a key, which includes a key shank, which at least in a part of its axial length includes a profile which is closed or semi-closed to define at least one cavity including a key coding. The lock includes a plug for receiving the key shank. The plug is rotatable with respect to a housing in the unlocked state of the lock and includes a keyway, which is defined by a predetermined geometry. At least one keyway shaping element is provided, which is formed separate from the plug and is fixed to the plug such that it is immovable relative to the plug when the key shank is inserted into the plug. A protruding portion of the at least one keyway shaping element protrudes into the keyway to redefine its geometry.

Abstract: An illustrative research support computing system maintains subject data representative of attributes for research subjects included in a potential subject pool for potential research studies. The system receives, from a client device, an input dataset representative of: 1) a set of parameters defining a research study to be conducted with respect to a research subject group, and 2) a set of criteria for research subjects that are to be included in the research subject group. The system designates a research subject included in the potential subject pool for inclusion in the research subject group based on the set of criteria, and receives research data detected for the research subject in accordance with the set of parameters. The system also provides an output dataset generated based on the research data detected for the research subject in accordance with the set of parameters. Corresponding methods and systems are also disclosed.

Abstract: A key including at least one coding cavity (55) defining a hollow geometry for coding the key. The geometry includes at least one internal undercut (60a, 60b). The lock for validating a key comprises blocking means (21, 22) coupled to a driving part (14) and validating means (25, 26) which are coupled to the blocking means so as to change the state of the blocking means when the key used with the lock has a correct coding. The validating means (25, 26) protrude at least partially into the key cavity of the lock in order to introduce the validating means at least partially into the coding cavity (55) of the key and to sense the inner face of the coding cavity.
