摘要:
A mobile radio communications network is disclosed in which zones may be defined for provision of location based services and applications. Various methods are also disclosed for using the defined zones in different ways for different applications. The methods include associating users with zones, updating users of zones with changes to the zones, controlling zone size and dynamically uploading zone profiles to users based on the user's geographical location.

Methods and systems for determining whether a mobile radio terminal is on or out of a zone in a radio communications network. The methods and systems provide for generating a profile representative of the zone using measurements taken by the mobile radio terminal and/or the network and/or using predicted values. A comparison is then made between subsequent measurements or values and the profile to make a determination as to whether the mobile radio terminal is in or out of the zone. The methods and systems are applicable to any zone-based application including differential call charging, security applications, buddy finder services, mobile gaming and location based services in general.
摘要:
A method and system for calculating the location of a mobile radio terminal in a radio communications network. The method provides for the collection of measurements of radio signal parameters at the mobile radio terminal which are then processed and transmitted to a network processor for calculating the location of the mobile radio terminal. The collected measurements may be filtered and subsets of the measurements may also be selected according to their suitability for particular applications.

Various method and apparatuses may be used to perform a procedure, such as a resection of a portion of the anatomy for preparation of the implants of a prosthetic. Various resecting member, including saw blades having selected geometries and shapes, can be used to assist in the resection of an anatomy to provide for implantation of a prosthetic. In addition, a cutting block assembly may be used to guide the resecting member. The cutting block assembly may be moveably mounted relative to the portion to be resected.

A surgical access assembly for positioning within an opening in tissue including an outer member positionable outside a patient and defining an opening therein to receive a surgical instrument. The outer member has a first portion and a second portion wherein at least one of the first and second portions is movable with respect to the other portion. The assembly also includes an inner member positionable within a patient and a flexible member extending between the inner member and outer member, wherein movement of one of the first and second portions of the outer member adjusts tension on the flexible member to retract tissue. A locking mechanism locks the outer member in a plurality of select expanded positions. The locking mechanism includes first engagement structure on the first portion engageable with the second portion and a slidable member movable to a locking position to retain the first and second portions in the select expanded position.
摘要:
The present invention relates to methods for producing a hyaluronic acid, comprising: (a) cultivating a Bacillus host cell under conditions suitable for production of the hyaluronic acid, wherein the Bacillus host cell comprises a nucleic acid construct comprising a hyaluronan synthase encoding sequence operably linked to a promoter sequence foreign to the hyaluronan synthase encoding sequence; and (b) recovering the hyaluronic acid from the cultivation medium. The present invention also relates to an isolated nucleic acid sequence encoding a hyaluronan synthase operon comprising a hyaluronan synthase gene and a UDP-glucose 6-dehydrogenase gene, and optionally one or more genes selected from the group consisting of a UDP-glucose pyrophosphorylase gene, UDP-N-acetylglucosamine pyrophosphorylase gene, and glucose-6-phosphate isomerase gene. The present invention also relates to isolated nucleic acid sequences encoding a UDP-glucose 6-dehydrogenase, UDP-glucose pyrophosphorylase, and UDP-N-acetylglucosamine pyrophosphorylase.
