A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.

A tissue penetration device and method of using same. The tissue penetration device may optionally include sampling and analyzing functions, which may be integrated. An embodiment provides control of a lancet used for sampling blood. Electric field coils or solenoids may drive the lancet using electromagnetic force. Advancement and retraction of a lancet may be controlled by a feedback loop monitoring the position and velocity of the lancet embodiments of the lancet driver can be configured to follow a predetermined tissue lancing profile. Embodiments of the invention include a lancet and method for using a lancet to maintain the patency of the wound tract once the lancet has cut into the skin.

A method is disclosed for remote monitoring of a premises, comprising the steps of operatively coupling a geographically remote client to a security system server which is capable of authenticating a user of the remote client, operatively coupling the remote client to a security gateway which is capable of managing the monitoring of the premises, activating a signal at the premises for notifying an occupant at the premises that remote monitoring is occurring, and transferring information between the security gateway and the remote client. The transfer of information between the security gateway and the remote client is controlled by the user of the remote client. The security gateway may be operably coupled to at least one camera at the premises and to at least one audio station at the premises.

A body fluid sampling system is provided for use on a tissue site. In one embodiment, the system comprises a cartridge; a penetrating member driver; a plurality of penetrating members arranged in a radial configuration on the cartridge wherein sharpened distal tips of the penetrating members point radially outward; wherein an active one of the penetrating members may be operatively coupled to the penetrating member driver, the penetrating member driver moving the active one along a path out of a housing having a penetrating member exit, into the tissue site, stopping in the tissue site, and withdrawing out of the tissue site; and a plurality of analyte detecting members, wherein at least one of the analyte detecting members is positioned to receive fluid from a wound created by the active one of the penetrating members, wherein the detecting members are not pierced by the active one of the penetrating members.

An acoustical imaging system for producing high resolution medical images provides a method and apparatus for obtaining accurate velocity characterizations of samples within the human body, and for obtaining high resolution images of the samples by utilizing the velocity characterizations of the samples within the human body. The acoustical imaging system also provides a method and apparatus for efficient use of switching channels whereby for a transducer array having a plurality of transducer elements, a set of receiver channels which number less than the number of transducer elements in the array are assigned to a selected portion of the plurality of transducers in the array, wherein for any predetermined set of transducers symmetrically located about a selected transducer, the predetermined set equal in number to the number of receiver channels in the system, each receiver channel in the set of receiver channels is only assigned to one transducer in said predetermined sampling set.

Local area networks having a high level of network integrity, error detection and correction, message security, expandability and flexibility are disclosed. The system is comprised of a loop controller which may communicate with a host through a standard interface such as an RS232 interface, and to which a plurality of nodes are coupled in a reconfigurable network. Each node has a plurality of modes controlled by the network controller to serve various functions depending upon requests from the controller and/or the needs or condition of the respective node from time to time. In particular, the first node is coupled to the controller through a pair of wires, with each successive node being coupled to the preceding node through a similar pair of wires. In one mode, the respective node monitors the incoming signal from the controller as repeated through any preceding nodes, and itself acts as a signal repeater for the next downstream node. The node also acts as a signal repeater to any return signal from the downstream node to pass that signal on toward the loop controller. In another mode the respective node provides its own signal on the return line for transmission toward the controller, and at the same time monitors the incoming return signal received from the next downstream node for repeating that signal on the upstream return line as soon as it completes its own transmission. In still another mode, the incoming signal is not repeated for the next node downstream but rather is looped back toward the controller.

Reconfigurable local area network

A power controller for electric locks which draw large startup current surges which controls and manages the energy of a pair of storage batteries to reliably operate such electric locks and provide steady-state power to auxiliary system components both with AC power present and in the absence thereof, so long as the stored charge in the batteries is able, to thereafter maintain a steady source of power to the system as long as possible, and to be self-starting upon the return of AC power, all without ever placing the electric locks in a partially unlocked or "hung" state. The two storage batteries are normally maintained charged through an AC power source, and both cooperate to provide the surge power. On loss of AC power, both still provide surge power so long as one can maintain the steady state power, and thereafter the other battery alone provides surge power so long as possible. On restart from a batteries discharged condition, surge power demand is tested periodically and immediately terminated when inadequate, thereby having minimal effect on the charging rate of the batteries.

Surge lock power controller

Reduced indicia keyboards for, and high security locks utilizing, key entry of a selectable lock code using a number of keys for the entry of each code element, which number of keys is less than the number of possible variations of that code element. Associated with each key is a code element display, viewable only by one operating the lock, to identify which particular value or variation of the code element is associated with that key at any particular time. By varying the association of the keys and the variations in the code elements, the sequence of key depressions and other observations with respect to the operation of the system without knowledge of the specific indicia associated therewith makes such observations useless in later attempting to operate the lock. Embodiments and methods of operating the same include a number of keys for entry of each code element which is less than the number of variations of that code element, the directional code element display or displays for viewing only by the user, and the non-repetitive and unpredictable operating order of the invention.
