Abstract:
In illuminated local areas occupants are actively detected to facilitate control of the illumination and possibly other local parameters such as temperature. The emitted light in each local area is uniquely modulated to identify the respective area. The modulated light is detected by any wearable occupancy detectors in the local areas, which transmit detector-locator signals to lighting control units, thereby identifying which local areas are occupied. These signals may also uniquely identify the respective detectors, thereby enabling a lighting system controller to determine the number and identities of the detectors in each local area.
Abstract:
A method for associating a group of lighting units in a wireless-controlled lighting system to respective buttons or other control elements on a remote control. Each of the lighting units transmits, via modulation of its own illumination light, a unique identification code for the respective unit. The remote control is successively positioned to receive the modulated light from each lighting unit and, at each position, the user activates a respective control element of the remote control for association with the lighting unit. The remote control then transmits to a control master for the group the unique codes and codes identifying the respective control elements with which they have been associated.
Abstract:
The present invention relates to a data transmission method, data transmission system and a cellular radio system employing information channels having at least two different capacities, the speech transmitted on said channels being coded in such a manner that on a channel having a higher capacity, essentially fewer symbols to be transmitted are coded from the same speech signal block than on a channel having a lower capacity. In order to extend the coverage area of the cellular radio system of the invention, the coverage area of the base station (BTS) comprises an inner coverage zone (50), on which frequency hopping is not applied, and an outer coverage zone (51), which employs an information channel having a lower capacity, the signal transmitted on said channel being speech coded according to a channel of a higher capacity, and that channel coding is performed on the speech coded data in such a manner that the number of symbols corresponds to the channel of a lower capacity, and frequency hopping being applied on said channel.
Abstract:
Techniques are disclosed related to cables that may be used within a medical device. According to one example, a cable may comprise multiple wires (200). Each wire may be formed of a biocompatible beta titanium alloy having an elastic modulus ranging from 30 GigaPascals (GPa) to 90 GPa and comprising at least two elements selected from a group of titanium, molybdenum, niobium, tantalum, zirconium, chromium, iron and tin. The cable may be heated (206) to a stress - relieve temperature of the beta titanium alloy to allow the cable to retain a desired configuration while remaining ductile. The cable may be included within a medical device, such as a medical electrical lead.
Abstract:
The present invention relates to novel synthetic substituted heterocyclic compounds and pharmaceutical compositions containing the same that are capable of inhibiting or antagonizing a family of receptor tyrosine kinases, Tropomysosin Related Kinases (Trk), in particular the nerve growth factor (NGF) receptor, TrkA. The invention further concerns the use of such compounds in the treatment and/or prevention of pain, cancer, restenosis, atherosclerosis, psoriasis, thrombosis, or a disease, disorder or injury relating to dysmyelination or demyelination or the disease or disorder associated with abnormal activities of NGF recptor TrkA.
Abstract:
An medical device shaft including an unbalanced braid reinforcement layer. The reinforcement layer may be an unbalanced braid by having a first set of strands and a second set of strands, the sets wound in opposing directions on a mandrel or on the device shaft. The first set and second set may have different numbers of strands, sizes of strands, or pitch, or combinations thereof. In some embodiments, the unbalanced braid increases contact area between the inner layer and the outer layer of the shaft without compromising the function of the braid. In other embodiments, the variations in strand size and number between the first set and the second set allows improved kink and torque performance in a reduced thickness braid layer. The improved shaft of the present invention may be incorporated into a wide variety of medical devices such as guide catheters, diagnostic catheters, balloon catheters, etc.
Abstract:
A disc head slider (36) includes a slider body with leading, trailing, inside and outside slider edges (50, 52, 54, 56) and a slider center line (58) extending from the leading slider edge (50) to the trailing slider edge (52). First and second raised side rails (60, 62) are formed in the slider body and each include an inside rail edge (108), an outside rail edge (110), a leading rail edge (50) and a trailing rail edge (112). The first and second raised side rails (60, 62) form first and second bearing surfaces (70, 72), respectively, which terminate prior to the trailing slider edge (52). A raised center rail (64) extends along the slider center line (58) and between the first and second raised rails (60, 62). First and second cavities (80a, 80b) are positioned between the raised center rail (64) and the first and second raised rails (60, 62), respectively. The first and second bearing surfaces (70, 72) each include a leading section (100), a waist section (104), a leg section (102) which extends from the waist section (104) to the leading section (100), and a trailing section (106) which extends from the waist section (104) to the trailing rail edge (112). The trailing section (106) widens from the waist section (104) toward the trailing edge (112) and includes a notch (113) positioned along the inside rail edge (108) which narrows the trailing section (106) at the notch (113).

Techniques related to coils for medical device are disclosed. One example coil may comprise multiple filars, each being formed of a biocompatible beta titanium alloy having an elastic modulus ranging from 30 GigaPascals (GPa) to 90GPa and comprising at least two elements from a group consisting of titanium, molybdenum, niobium, tantalum, zirconium, chromium, iron and tin. At least one of the multiple filars may be electrically insulated one from another. A structural body, such as a lead body, may carry the coil. One or more filars may carry a low- resistance core. A method for forming the coils is also disclosed. Further, a medical electrical lead comprising such a coil is also disclosed.
