Inventor: GOVARI ASSAF
IPC: A61B5/06
Filed: 2004-11-08
Abstract: A method is provided for tracking an object, including positioning a radio frequency (RF) driver to radiate an RF driving field toward the object, and fixing to the object a wireless transponder that includes a power coil and at least one sensor coil. The method also includes receiving the RF driving field using the power coil and storing electrical energy derived therefrom. A plurality of field generators are driven to generate electromagnetic fields at respective frequencies in a vicinity of the object that induce a voltage drop across the at least one sensor coil. A digital output signal is generated at the wireless transponder indicative of the voltage drop across the sensor coil, and the generation of the digital output signal is powered using the stored electrical energy. The digital output signal is transmitted from the wireless transponder using the power coil, and the transmission of the digital output signal is powered using the stored electrical energy. The digital output signal is received and processed to determine coordinates of the object.

Title: Screw cap for pressurised containers
Inventor: GASSNER OKTEN
IPC: B65D41/04
Filed: 2003-09-24
Abstract: The invention relates to a screw cap for containers with a threaded neck, in particular PET bottles designed to hold beverages containing CO2. Said cap comprises a top plate (1), an approximately cylindrical cap jacket (2), provided with an interior thread (3), an approximately cylindrical inner sealing collar (4), emanating from the top plate (1) and having an annular continuous region that projects radially outwards and an essentially cylindrical outer sealing collar (5), which concentrically surrounds the inner sealing collar (4). The maximum outer radius of the inner sealing collar and the minimum inner radius of the outer sealing collar differ only slightly, preferably by less than 2 mm and in particular by less than 1 mm and the inner and outer sealing collars (4, 5) are designed to receive the upper region of a bottle neck (11) in the annular gap formed between said collars. The aim of the invention is to provide a screw cap, which in general retains the excellent sealing properties of the known screw cap, even in extreme environmental conditions and is at the same time capable of limiting the pressures that occur in a container with a screw cap, without losing its sealing function. To achieve this, the cap is provided with devices (6, 7), which limit the axial depth of penetration of the edge of a bottle neck (11) into the gap between the inner (4) and the outer sealing collar (5).

Abstract: A flexible, integrally formed tie strip for forming a loop when passed through itself comprises a plurality of identical cells formed in a strip, the cells forming generally loop-shaped enclosed apertures (10) bounded by wall portions of the cells, each aperture allowing the passage of further cells through it.  The cells are further provided with one or more latching members (11) allowing passage of one cell through another in one direction but preventing passage of the cell in the reverse direction. The walls (9) bounding the apertures can be folded to a saddle shape about radial and longitudinal axes, so as to increase the width of the aperture without stretching the material of the walls, thereby facilitating the passage of a penetrating cell through the aperture of another cell. Moreover the penetrating cell is designed to fold so as to pass through still more easily. This three-dimensional deformation is promoted by a notch (15) in the rear of each aperture wall.
