Abstract: A well drilling method can include detecting a drilling event by comparing a parameter signature generated during drilling to an event signature indicative of the drilling event, and automatically controlling a drilling operation in response to at least a partial match resulting from comparing the parameter signature to the event signature. A well drilling system can include a control system which compares a parameter signature for a drilling operation to an event signature indicative of a drilling event, and a controller which controls the drilling operation automatically in response to the drilling event being indicated by at least a partial match between the parameter signature and the event signature.

Abstract: A compound of formula (I) wherein, X and Y independently bind TSPO, wherein X and Y are the same or different; and L is a linker that links X to Y; or a salt or solvate thereof. For preference, X and Y may be (II) or (III). The compounds may be radiolabeled with a radioisotope. Also methods for diagnosing or treating TSPO related disorders such as neurodegenerative disorder, inflammation or anxiety, eg. Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, multiple system atrophy, epilepsy, encephalopathy, stroke, brain tumour, anxiety, stress, emotional disturbances or cognitive impairment, glioblastoma, ischemic stroke, herpes encephalitis, HIV, amyotrophic lateral sclerosis, corticobasal degeneration, cancer, depression, an auto-immune disease and an infectious disease.

Abstract: An apparatus for automatically dispensing a fluid includes a container adapted to carry a supply of fluid, and a valve connected to said container, wherein actuation of said valve dispenses the fluid. Also included is an apparatus position indicator proximally associated with the container and an object sensor positioned near the valve. The object sensor monitors an area below where the valve dispenses when open and upon detection of an object opens said valve. Initial positioning of the apparatus triggers the apparatus position indicator to generate an appropriate signal until said object sensor is properly positioned. Once positioned the device may be permanently secured. A control circuit within the apparatus also allows programming of lighting indicators, dispense cycle size, and dispense quantities. The control circuit also provides for overload protection, motor braking and RF shielding.

Abstract: A dispensing system is disclosed which utilizes an electronically powered key device and/or identification code associated with a refill container to preclude the need for mechanical keys. The system utilizes a near field frequency response to determine whether a refill container is compatible with a dispensing system. In particular, the refill container is provided with a coil terminated by one of a number of capacitors. The container is received in a housing that provides a pair of coils that are in a spatial relationship with the installed refill container's coil. By energizing one of the housing's coils, the other coil detects a unique electronic signature generated by the container's coil. If the signature is acceptable, the dispensing system is allowed to dispense a quantity of material. The system also provides a unique latching mechanism to retain the container and ensure positioning of all the coils.
