Title: Weaving reed dent spacing arrangements
Inventor: WANG PAMELA C
IPC: D03D49/68
Filed: 1998-01-19
Granted: 2006-06-13
Abstract: A weaving tried (3) having a plurality of reed dents (14) fixed in certain positions and which may be located in a reed baulk (6). The reeds may be plain reeds or reeds, with any profile, usable virtually on any loom. The dents are formed of wires and spaces (10) and are variably spaced. The variable spaces are formed by varying the thickness of the wires, the width of the spaces, or a combination thereof to produce fabrics with a desired warp density across the entire width of a giv en fabric. The reed may produce a consistent warp end density which improves the mechanical properties of a given fabric and also provides virtually consistent air permeability across the width of the finished fabrics. The reed can also produce changes in warp end density in a given fabric for certain desired effects. A rotary type reed (14) and weaving rotor (19) for multiple-shed looms are also disclosed.</SDO AB>

Title: A method and an arrangement relating to temperature sensing in electric circuitry
Inventor: KELLERMAN MICHAEL
IPC: G01K7/24
Filed: 1999-08-20
Granted: 2007-07-17
Abstract: It is shown a method and an arrangement for determining a temperature of a battery pack (100) connected via a single communication line (107) to an electric device (101). The battery pack (100) and electric device (101) both comprise control and signaling means (105, 108) capable of exchanging digital signal sequences. The battery pack (100) comprises an impedance unit (112) having a temperature dependent impedance value. The method comprises steps of signaling between the battery pack (100) and the device (101). This is followed by a sequence of steps where the control and signaling means (105) of the battery pack (100) is disconnected from the communication line (107) and the temperature dependent impedance unit (112) is connected to the communication line (107). Electric current is supplied to the impedance unit (112) via the communication line (107) and a voltage level is measured on the communication line (107). Then an impedance value is calculated based on the supplied current level and the measured voltage level. An interpretation of the calculated impedance value as a temperature of the battery pack (100) is then performed, followed by disconnecting the temperature dependent impedance unit (112), and reconnecting the control and signaling means (105) of the battery pack, to the communication line (107).
