摘要:
A Write Broadcast system and method uses a base station to write sent data to all or some selected number (sub group) of tags in a base station field simultaneously. By unselecting the tags that have been successfully written to, and requesting a response from the remaining tags in the field (or sub group), the system determines, by receiving a response to the request, that there are tags in the field (sub group) that were unsuccessfully written to. Another Write Broadcast signal is sent to these tags. The system is useful for quickly (simultaneously) “stamping” information on the tag memory of a large number of tags in the field of the base station.
摘要:
A system and method is disclosed for selecting certain subgroups of radio frequency (RF) tags for querying, communicating, and/or identifying by a base station. The base station sends commands to a group tags within a RF field of the base station. The tags use control logic to determine whether or not they meet certain criteria sent out by the commands. This may cause the tags to change state which either prevents or allows a given tag to participate in an identification process. In this way, a given subgroups of tags meeting certain criteria can be selected for querying, communicating, and/or identifying.

A master entity is capable of broadcasting commands to a plurality of three-state-selection machine slaves. Transitions from one state to another are effected on instruction from commands in a sequence of commands broadcast from the master. Slaves move to another state when they satisfy a primitive condition specified in the command. By moving slaves among the three sets, a desired subset of slaves can be isolated in one of the sets. This desired subset of slaves then can be moved to one of the states that is unaffected by commands that cause the selection of other desirable subsets of slaves. In the embodiments of the incorporated U.S. Pat. No. 5,673,037, certain subgroups of radio frequency (RF) tags are selected for querying, communicating, and/or identifying by commands from a base station. Commands from the base station may cause the tags to change state which either prevents or allows a given tag to participate in an identification process. In this way, a given subgroup(s) of tags meeting certain criteria can be selected for querying, communicating, and/or identifying.
摘要:
An exemplary embodiment uses a novel adaptation of a tree splitting algorithm applied to Radio Frequency (RE) tagging technology to identify many tags in the RF field of a base station. The embodiment uses the tree splitting algorithm to identify a single tag in a field of a plurality of radio frequency tags. Once the single tag is identified, the identified tag is placed in a Data_Exchange state where the base station can access data from the tag memory by using information that identifies the tag.
摘要:
A method for reducing odor is provided. The method comprises forming a coordination complex between a transition metal and a polydentate compound, and contacting the coordinated complex with an odorous compound. The transition metal provides one or more active sites for capturing the odorous compound. In some embodiments, the polydentate compound may be a polyalkylimine, such as polyethyleneimine, polypropyleneimine, or a dendrimer thereof.
摘要:
A vaginal treatment composition that employs a therapeutic agent to inhibit and/or treat vaginal infection is provided. The therapeutic agent is capable of inhibiting and/or killing Gardnerella (e.g., Gardnerella vaginalis), Candida (e.g., Candida albicans), and/or Trichomonas (e.g., Trichomonas vaginalis) pathogens. Desirably, such antimicrobial efficacy is achieved without substantially inhibiting the growth of Lactobacillus acidophilus. For instance, sugars and/or sugar alcohols may be employed in the present invention as a therapeutic agent for inhibiting and/or treating vaginal infection. In one particular embodiment, D-xylitol is used as the therapeutic agent.
摘要:
A therapeutic article includes a skin contact layer having a plurality of fibers forming a plurality of point-bearing surfaces configured for wear against a user's skin; a personal care composition disposed proximate the fibers; an external layer attached to the skin contact layer; and an intermediate layer interposed between the skin contact layer and the external layer, the intermediate layer being configured to activate the personal care composition, the external layer being configured to direct the activated personal care composition through the skin contact layer to treat the user.
摘要:
The invention provides a polymer adapted for use in melt processes, the polymer having thermally reversible and non-thermally reversible bonds which polymer is adapted to evanesce at an elevated temperature and revert to a thermally reversible bond upon cooling to ambient temperature so that the polymer is adapted, upon being heated to the elevated temperature, to dissociate into melt processable polymeric fragments and, upon being cooled to ambient temperature, to re-associate.
