Abstract: According to the invention, a method and an arrangement are provided for digital radio transmission of data between a fixed station (1) and at least one mobile station (2, 3) at one of a plurality of carrier frequencies (f1, f2, ...), the data being transmitted in time slots (Z1, Z2 ...) using time-division multiplex method (TDMA) and, in particular if so-called slow hopping RF modules are used, the change from one carrier frequency to another carrier frequency requiring at least a time period corresponding to one time slot. According to the invention, the data are transmitted in in each case two successive active time slots (Z1, Z2) which are followed by an inactive time slot, in which no data are transmitted. The transmission in two successive time slots (Z1, Z2) in this case takes place at the same carrier frequency. If the method or the arrangement according to the invention are used for the purpose of matching the DECT standard to the US-American ISM band, six time slots for transmitting from the fixed station to at least one mobile station can be followed by six time slots for transmitting from the at least one mobile station (2, 3) to the fixed station (1).

Abstract: Methods and apparatus are described for forming a window of optimum dimensions in casing wall. A window of maximum width is cut when the center line of the mill tool is located inside of the inner diameter of the casing where a maximum amount of casing is drilled away by the mill tool. A whipstock is described which deviates the mill tool outwardly so that the center line of the mill tool is in approximately this position. The whipstock then maintains the mill tool at this approximate location until a window of desired length is cut having a substantially maximum width.

Title: Body weight supports and teaching aid
Inventor: EASTWOOD OWEN
IPC: A63C11/00
Filed: 2000-06-30
Granted: 2007-01-02
Abstract: The invention relates to body supports and teaching aids particular for use during skiing. Skiing to greater or to lesser degrees imposes strains on the muscles of the skier causing fatigue and encouraging a skier to adopt an incorrect stance or posture not conducive to good and correct skiing. The object of the invention is to provide a simple and effective body support and teaching aid that is effective during skiing and does not need to be removed during a temporary cessation of activity but allows substantial freedom of movement of the legs during walking and sitting. This objective is met by a construction comprising a first (upper) member adapted for location against the thigh area of the leg, a second (lower) member adapted for location against the calf area of the leg, a pivotal connection between the first and second members, the second member being connectable to the boot of a user, load bearing means located on the support to provide a resistance to pivotal movement between the first and second members, and said load bearing means being deactivatable to permit substantially free pivotal movement between the first and second members.

Abstract: In a metallurgical furnace of the type for re-heating metal billets and slabs, a pair of composite refractory tiles for insulating fluid-cooled structural members of the furnace. The tiles are a composite of a cast refractory shell which extends radially inward at selected portions to contact the furnace member.      Attachment assemblies are embedded in the cast refractory shell and maintain proper alignment of each tile with the furnace structural member. In portions of the tile where contact with the furnace member is not made, a ceramic fiber insulating blanket fills a hollow between the refractory shell and the furnace member.      Incorporating the ceramic fiber insulating blanket into each tile decreases furnace heat loss as compared to solid cast refractory tiles of comparable thickness.

Abstract: In a MIMO system the signals transmitted from the various antennas are processed so as to improve the ability of the receiver to extract them from the received signal even in the face of some correlation. More specifically the number of bit streams that is transmitted simultaneously is adjusted, e.g., reduced, depending on the level of correlation, while multiple versions of each bit stream, variously weighted, are transmitted simultaneously. The variously weighted versions are combined to produced one combined weighted signal. The receiver processes the received signals in the same manner as it would have had all the signals reaching the receive antennas been uncorrelated. The weight vectors may be determined by the forward channel transmitter using the channel properties of the forward link which are made known to the transmitter of the forward link by being transmitted from the receiver of the forward link by the transmitter of the reverse link or the weight vectors may be determined by the forward channel transmitter using the channel properties of the forward link and the determined weight vectors are made known to the transmitter of the forward link by being transmitted from the receiver of the forward link by the transmitter of the reverse link. The channel properties used to determine the weight vectors may include the channel response from the transmitter to the receiver and the covariance matrix of noise and interference measured at the receiver.

Abstract: A packaging process is disclosed which includes the steps of providing a tray, providing an upper film which includes a sealant layer which is sealable to the tray, orienting the film to an orientation ratio of from about 6.0:1 to about 16.0:1, positioning a high profile product on the tray, extending the upper film above the tray and product, drawing the upper film into a concavity by differential pressure, maintaining the concave shape of the upper film while heating the film, removing gases from the space between the upper film and the tray and product, introducing a desirable gas into the space, releasing the upper film such that it shrinkis toward the product and the tray while the desirable gas is retained within the space and prevents close contact of the film with the lowermost portions of the product, and sealing the upper film to the flange of the tray, wherein at least the step of heating the film shrinks the film, thereby tensioning it onto and across the underlying product. The resultant package of the high profile product provides an in-store overwrap appearance.

Title: Method for differentiating between burdened and cracked ultrasonically tuned blades
Inventor: FRIEDMAN ALLAN L
IPC: A61B17/32
Filed: 2001-10-17
Granted: 2010-09-28
Abstract: A method for differentiating between ultrasonically tuned blades which are broken or cracked, and blades which are gunked by evaluating measured impedance differences when a system is first excited with a low displacement signal and then with a high displacement signal. The method is performed irrespective of the age of the hand piece/blade, the temperature or specific type of hand piece or blade, and is not affected by self healing effects of slightly cracked blades. Moreover, the method facilitates the quantifiable determination of the amount of gunk on the blade. Absolute impedance measurements of the transducer or blade are unnecessary. Instead, only relative impedance measurements are required, which greatly simplifies the measuring criteria. This provides a way to measure the amount of gunk accumulation, and thereby a way to calculate/estimate the amount of heat generated at the sheath, as well as a way to calculate/estimate the amounts of degradation to the load curve of the ultrasonic system.

Abstract: A method and apparatus for monitoring fiber optic communications involves providing a space between a first end of a first optical fiber and a second end of a second optical fiber. A reflector is movable between a retracted position and an active position. In the active position, the reflector is positioned in the path of an optical signal beam passing through the space between the first optical fiber and the second optical fiber to reflect a portion of the optical signal beam as a tap signal. The reflector is selectively moved between the retracted position and the active position. This enables the tap signal to be selectively turned off and on. It also enables the portion of the optical signal beam reflected to be selectively adjusted.
