Abstract: A method of determining the presence or absence in a sample of a biomarker, the method comprising the steps of (a) providing a porous substrate which carries an antigen; (b) contacting the substrate with the sample; (c) contacting the substrate with a composition comprising a secondary antibody; and (d) observing the substrate. The method may enable a very quick, simple test to be carried out to determine whether or not a particular sample contains a biomarker, for example an antibody indicative of infection with a mycobacterial disease. A kit and a device for determining the presence or absence in a sample of a biomarker are also described.

Abstract: A method of determining whether an individual is infected with mycobacteria. The method comprising the steps of (a) providing a system which comprises at least two different mycolic-acid derived antigens; (b) introducing a sample obtained from the individual into the system and into contact with each of the at least two different mycolic-acid derived antigens; and (c) detecting the presence or absence of the binding of a biomarker in the sample with each antigen in the system. The method may be particularly suitable for determining the presence or absence of a disease antibody indicative of infection with any disease caused by infection with mycobacteria, for example tuberculosis, leprosy, pulmonary disease, burili ulcer, Johne's disease and bovine tuberculosis. A kit and device are also described. The present invention may provide an over the counter device to allow individuals to check on a routine basis that they have normal immune responses.

Abstract: Methods and systems are provided for varying the volume of an engine intake system to increase the volumetric efficiency of the engine.

Abstract: Disclosed examples include methods and circuits to drive a haptic actuator, in which a single input signal from a host device has a first state representing a command to drive the actuator and a second state representing a command to stop the actuator. A control circuit provides a drive control signal to a driver circuit to drive the haptic actuator in response to the control signal transitioning to the first state, and to stop the haptic actuator in response to the control signal transitioning to the second state. A timer circuit places the circuit in a low power mode a predetermined time after the control signal transitions to the second state, or the control circuit places the circuit in the low power mode in response to a feedback signal indicating that the actuator has reached a stopped condition.
