  • Publication number: 20240121640
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit a set of reference signals spanning a channel to a user equipment (UE), where each of the reference signals is associated with one of a set of transmit beams. The UE may measure a signal quality of each of the set of reference signals. In some cases, each measured signal quality may correspond to one of a set of subbands of the channel and one of the set of transmit beams. The UE may then transmit an indication of at least one signal quality associated with one of the set of subbands and one of the set of transmit beams. In some cases, the UE may indicate the at least one signal quality according to a configuration that may be indicated by the base station or selected by the UE.

  • Patent number: 9717412
    Abstract: A wireless fetal and maternal monitoring system includes a fetal sensor unit adapted to receive signals indicative of a fetal heartbeat, the sensor optionally utilizing a Doppler ultrasound sensor. A short-range transmission unit sends the signals indicative of fetal heartbeat to a gateway unit, either directly or via an auxiliary communications unit, in which case the electrical coupling between the short-range transmission unit and the auxiliary communications unit is via a wired connection. The system includes a contraction actuator actuatable upon a maternal uterine contraction, which optionally is a EMG sensor. A gateway device provides for data visualization and data securitization. The gateway device provides for remote transmission of information through a data communication network. A server adapted to receive the information from the gateway device serves to store and process the data, and an interface system to permits remote patient monitoring.

  • Publication number: 20150218179
    Abstract: A process for formulating certain epothilone analogs for parenteral administration is disclosed wherein the analog is dissolved in a mixture of at least 50% by volume tertiary-butanol in water, the mixture is lyophilized, the resulting lyophilized product is packaged in one vial with a sufficient amount of solvent comprising anhydrous ethanol and a suitable nonionic surfactant in a second vial. All steps are carried out with protection from light. In use, the contents of the second or diluent vial are added to the lyophilized product and mixed to constitute the epothilone analog and the resulting solution is diluted with a suitable diluent to produce a solution for intravenous injection containing the epothilone analog in a concentration of from about 0.1 mg/mL to about 0.9 mg/mL. A preferred surfactant is polyethoxylated castor oil and a preferred diluent is Lactated Ringer's Injection.

  • Patent number: 8595302
    Abstract: A system and method for mediating the routing of asynchronous messages includes routing the asynchronous message to a first recipient, determining whether the first recipient opened the asynchronous message, and re-routing the asynchronous message to a second recipient who is qualified to receive and respond to the message if the first recipient fails to open the message (i.e., read, listen, display, act upon the message). In an embodiment, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline automatically imposed by the system when the message is of a certain type. In an embodiment, a mediator monitors if any recipient accepts responsibility for the asynchronous message and informs the other recipients that the asynchronous message may be deleted from their message queues.

  • Patent number: 8258041
    Abstract: A method of fabricating metal-bearing structures in an integrated circuit such as metal-polysilicon capacitors using conductive metal compounds. Defects due to organometallic polymers formed during the etch of a hard mask material are minimized by using a process that includes a plasma etch for the hard mask that achieves a predominantly chemical character using a fluorine-based etch chemistry. Using a low-temperature liquid-phase strip of the hard mask photoresist instead of an ash prevents further cross-linking of polymers formed during the plasma etch. Etching the metal-bearing material using a hot fully-concentrated mixture of ammonium hydroxide and hydrogen peroxide allows short etch times that are particularly shortened for tantalum nitride films deposited with a nitrogen concentration of about 30 percent or greater.

In an aspect, the second recipient is selected based upon the role that the second recipient performs within the system. In another aspect, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline imposed by the message sender. In another aspect, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline automatically imposed by the system when the message is of a certain type.

  • Publication number: 20110053372
    Abstract: A method of removing photoresist from a surface during the manufacture of an integrated circuit. Organometallic polymers and monomers are formed during the etch of a hard mask material defining the locations of a metal-bearing film, such as tantalum nitride, when photoresist is used to mask the hard mask etch. These organometallic polymers and monomers as formed are not fully cross-linked. A liquid phase solution of sulfuric acid and hydrogen peroxide used to remove the photoresist also removes these not-fully-cross-linked organometallic polymers and monomers, thus preventing the formation of stubborn contaminants during subsequent high temperature processing.
