Abstract: Implantable devices and associated devices, systems, and methods are disclosed herein. The devices and systems of the present technology may be equipped with electronic components that provide a platform for remote patient and/or device monitoring. Operation of an implantable devices and/or one or more components thereof can be modulated over time depending on certain conditions. This modulation can include limiting wireless data communication with external devices to certain time intervals, varying parameters of data collection by sensing elements, and/or controlling power supplied to electronic components, for example. In some examples, an implantable device may operate in a low-power standby state in which data is obtained via sensing elements and stored in local data storage, but the data is not wirelessly transmitted to an external device until a modulation signal is received by the implantable device, causing the implantable device to change to a more active power state.

Abstract: The specification discloses apparatus and a process in which the stack of concrete or hard rubber spacer rings used in raising manholes is eliminated. It is replaced with a sleeve which is taller than the required distance between the top of the manhole and the level at which the casting and manhole cover are to be finally located, but which is sufficiently flexible in a vertical direction that when a casting is located in the top of the sleeve, the sleeve compresses downwardly. The height of the casting is fixed by a casting support resting on the pavement base coat or other base surface to which the final pavement will be applied around the casting. The sleeve is sufficiently stiff in a lateral direction that it does not collapse inwardly when backfill is packed in and around the exterior of the sleeve. The casting support is removed and the final layer of pavement is applied over the base surface.

Abstract: Apparatus and methods are disclosed foe phase-sensitive measurements of optical signals utilising semiconductor array detectors such as CCD sensors. The sensors are operated under conditions where changes are moved bi-directionally according to a predetermined scheme and/or the spatial extent of charge collection from pixels of the array is controlled. Applications of phase-sensitive detection to decay-time-related measurements of luminescence are presented.

Abstract: The invention provides a low cost ring signal and pulse dial signal detector which can be used in conjunction with a device adapted for carrying out digital communication over a telephone network. The invention comprises a zener diode coupled in series with a snubber circuit that is connected in parallel to the switchhook of the telephone communication device. When the switchhook is open circuited, the zener diode creates high frequency harmonics of any signals on the telephone line such as ring and pulse dial signals. Certain of the harmonics of the ring and pulse dial signals will be within the bandwidth at which the telephone communicating device is tuned to receive communications. Therefore, since the telephone communicating device is already adapted to receive signals at a specified frequency within the communication bandwidth of the telephone network (300-3000 Hz), the addition of the zener diode prvides all of the apparatus necessary to allow for ring and pulse dial signal detection.
