Title: A loop antenna for mobile handset and other applications
IPC: H01Q5/10
Filed: 2010-10-15
Abstract: A folded loop antenna 1 for mobile handset applications comprises a conductive track 2 formed on the surfaces of a dielectric substrate, where first and second adjacent terminals 3, 4 are formed on a first surface of the substrate. The conductive track 2 extends in generally opposite directions 5, 6 from the respective terminals 3, 4. The track 2 then extends in a direction 8 towards an edge of the substrate before passing to a second surface of the substrate where the track follows a similar pattern to those on the first surface before connecting at a conductive arrangement 13. The conductive arrangement 13 extends into a central part of the loop formed by the conductive track 2 on the second surface of the substrate and may comprise capacitive and inductive elements in the form of discrete or distributed components which provide a series complex structure. The antenna 1 may have the first and second terminals 3, 4 connected to a feed and ground, respectively. Alternatively, the terminals 3, 4 may both be connected to ground with a further driven antenna arranged to drive the loop antenna via inductive and/or capacitive coupling. The antenna 1 may include parasitic and/or branching elements and can be a multi-mode formation which can operate in several frequency bands.

Patent IT-TV20010015-D0 (IT)
Inventor: MARCHETTO OSCAR
IPC: E05F15/12
Filed: 2001-02-02
Abstract: The invention relates the control of a gate (10) having at least one wing (11B) electrically operated preferably by a geared motor (13B) with a single-phase asynchronous motor. A control unit (20) detects and memorize during the calibration procedure the opening and closing times by computing the opening and closing working time intervals within which an intervention is necessary in order to avoid dangerous situations. During normal opening and closing operation, at the beginning of the stored time intervals, the unit (20) detects the steady current (Io) and computes a limit value (Io +  DELTA I) against which the instantaneous current (I) flowing into the geared motor is compared. When a value I is detected that is greater or equal to lo +  DELTA I, due to an obstacle for the movement of the wing, the geared motor automatically inverts its sense of rotation. USE : gates and doors with one or more wings, even different from each other regarding size and movement. ADVANTAGES : simplicity and low construction and calibration cost. Reliable operation. <IMAGE>

Title: Wound drain catheter
Inventor: BLAKE LARRY WEBSTER
IPC: A61M1/00
Filed: 1982-02-26
Granted: 1988-12-08
Abstract: The wound drain catheter of the present invention is comprised of a drain portion connected to an outflow tube portion.

This drain has a uniform cross-sectional area and is preferably made from a silicone elastomer having a durometer shore between 40 and 70 shore A. Such uniform cross-sectional area provides added strength to prevent the drain from breaking during its removal from the patient's body, and the silicone elastomer provides sufficient elasticity to permit the cross-sectional area of the drain to decrease by at least 30 percent when a pulling force is applied thereto, thereby reducing the gripping force of tissue surrounding the wound.

Title: Circuit arrangement of putting into operation the remote power supply to electricity consumers
Inventor: ZIEGLER ALFRED DIPL ING
IPC: H04B17/40
Filed: 1983-04-29
Granted: 1987-02-12
Abstract: For remote feed of a group of electrical users connected in series in a closed loop, a dc voltage is applied to the loop in a polarity opposite to a normal feed voltage in order to determine whether interruptions are present, even if a human body is shunting the loop at the interruption. Each of the users has a diode connected in parallel to its inputs which is polarized such that when the test voltage for creating a test current is applied, substantially only a resistance of the loop is measured exclusive of the users. A loop resistance is determined from a measurement of the test current and the loop resistance is compared to a test resistance set lower than a human body resistance. If the loop resistance is lower than the test resistance, then normal remote feed current is applied to the loop since no interruptions exist. If the loop resistance exclusive of the users is of a same magnitude or greater than the human body resistance, then shunt arms are employed in the loop comprised of resistors and diodes to lower the loop resistance during feed of test current so as to reliably detect whether an interrupt location is present.
