The ability of an ultrasonic system to sweep and lock onto a resonance frequency of a blade subjected to a heavy load at startup is improved by applying a high drive voltage or a high drive current while systematically increasing the level of the applied signal. Increasing the drive signal to the hand piece results in an improved and more pronounced “impedance spectrum.” That is, under load, the increased drive signal causes the maximum phase margin to become higher and the minimum/maximum impedance magnitude to become more pronounced. Increasing the excitation drive signal to the hand piece/blade at startup significantly alleviates the limiting factors associated with ultrasonic generators, which results in an increase of the maximum load capability at startup.

This invention relates to a system and method of monitoring hygiene standards compliance in a medical facility in which there is provided a surveillance network having a monitoring unit 3 and a plurality of mobile network units 7. There may additionally be provided a plurality of fixed network units 5. The monitoring unit 3, mobile network units 7 and fixed network units 5 are connected by way of a Wireless Personal Area Network (WPAN), in this case a ZigBee network. Identification signals are sent from the mobiles network units 7 to the monitoring unit 3 and the monitoring unit stores the identification signals in memory and generates a hygiene standards compliance profile for an individual associated with a particular mobile network unit. The hygiene compliance profile may provide information relating to the number of times that a particular individual washed their hands to information regarding the patients that that individual came into contact with over the course of a shift. Reports on the behaviour of individuals or groups of individuals may be generated.

Embodiments of the invention relate to cellular wireless networks and are particularly suited to networks including different types of base stations. So-called femtocell types of base stations are typically deployed within a subscriber's premises and operate at low transmit power, providing a very limited area of wireless coverage. A femtocell is typically deployed within the area of wireless coverage of a conventional macrocell, occupying the same frequency spectrum and timeslots as the macrocell. A problem can be presented to a user equipment terminal that is close to the femtocell but unable to gain access to it, because the transmissions from the femtocell may appear as interference to the user equipment terminal, preventing it from accessing the macrocell which it could otherwise access. A cellular wireless network according to an embodiment of the invention employs a method of allocating radio resource to femtocells so that the transmissions from femtocells do not occupy the same radio resource blocks as those used by the macrocell for signalling; embodiments of the invention thereby prevent interference associated with signalling to cause a connection to be lost, or prevent a connection being set up.

A system for accurate measurement and monitoring of AC or DC electrical current flowing through electrical conductors includes one or more current sensors, a receiver, and one or more calibration signal generators (“CSG's”) that can be plugged into outlets or otherwise coupled to the conductors so as to add automated, time-varying calibration signals to the conductors, such as current pulses or pulse patterns. The sensors are placed on a circuit breaker panel, around a cable, or otherwise near the conductors. The receiver distinguishes the calibration signals by their timing, pulse patterns, frequencies, or other time-varying features, uses their known amplitudes to calibrate the sensitivity of each sensor to each conductor, and determines the current flowing in each conductor. Among other applications, the invention can monitor building current usage, CO and data center power usage and distribution, and power line current leakage, and can calibrate invasive and/or non-invasive current sensors.

Some bus protocols are useful for management of peripheral devices that exist on a computer's system bus. Such bus protocols include the industry standard architecture bus (ISA), peripheral component interconnect (PCI), PCI express (PCIe), etc. The usefulness of such protocols for control messages, interrupt management and more is limited to the short distances over which the protocols operate, usually measured in inches. The use of longer distance transport protocols, such as Ethernet to encapsulate and transport bus protocol messages allows the advantages of the short distant protocols to be used to control remote devices. A master device, with a controller or processor, may be used to manage the operation of a slave device using the bus or control protocol. Such management may include button presses, indicator lights, slave device configuration, etc. The slave device may have a low cost controller or ASIC to provide real-time operational functions, such as routing.
