摘要:
Tracheal tubes having an integrated calorimetric CO2 indicator are provided. In certain embodiment, the integrated CO2 indicator is selectively sealed from the remainder of the tracheal tube by a removable sterilization barrier. Also provided are CO2 indicators that exhibit long lasting, breath-to-breath dynamic color change and are storage stable. The devices and compositions of the invention find use in a variety of applications, e.g. in emergent intubation of a subject. Also provided are methods of making the devices and compositions, as well as kits that include the devices and/or compositions of the invention.

The invention generally relates to a stopper for controlling the flow of molten metal from a metallurgical vessel like a tundish. Any references made hereinafter, relating to the design, construction and/or function of the stopper, refer to the typical use position of such stopper, i.e. a vertical oriented position.

A chemical vapor deposition reactor is provided. The chemical vapor deposition reactor includes a deposition chamber, a substrate within the deposition chamber, at least two inlet ports extending into the deposition chamber for supplying a first and a second gases to the deposition chamber respectively and a particle source for supplying a plurality of solid particles to the deposition chamber. The first gas reacts with the second gas to form a film incorporating the plurality of solid particles upon the substrate. Films with composition varying across the growth direction are produced by the chemical vapor deposition reactor without the use of mask layers.

An enhanced email system that will allow for marketing to anonymous consumers, protecting their privacy and reducing unwanted marketing. Consumers register interest in products and services as well as enough information to ensure delivery of communications and prevent abuse. Consumers have the ability to terminate communication at any time as well as the option to communicate directly. Merchants have the ability communicate confidentially with groups of consumers or individual ones. Categorization of wanted versus unwanted by use of sender identification. The system will be monitored for abuse and actions will be taken to prevent abuse.
摘要:
An enhanced email system that will allow for categorization of wanted email based on relationships between senders and receivers. Modified email servers and clients will deliver and/or sort email based on defined relationships between senders and receivers or intermediaries and the receivers preferences. This means email delivery or sorting is based on a web of relationship. Support for encryption to multiple members of a group is supported by a system of dynamic delivery and maintenance of group keys.

A voltage down converter 10 for providing a supply voltage and current to a device, such as a semiconductor device. The voltage down converter includes a first circuit 12 that supplies steady state or “DC” current to the device, and a second circuit 14 that supplies the fluctuating or “AC” current to the device. The first circuit 12 includes a first comparator 18 that drives a first transistor P1 to supply most of the steady state current. The second circuit 14 includes a second comparator 20, which is larger than the first comparator 18, and which drives a second transistor P2, which is smaller than the first transistor P1, to supply the fluctuating current to the device. The converter 10 further includes a feedback circuit 16 for controlling the supply voltage.

An actuated toy device including a recognizable character such as a Santa Claus doll reclining in a bed. The doll character chest portion is moved up and down vertically by a battery-powered gear unit through a first linkage mechanism provided in a housing attached below the bed, so as to simulate breathing action by the doll. The toy device includes an audio unit mounted in the housing. Also a second linkage mechanism is provided and arranged to periodically raise the doll head and torso portions upward from a reclining position to a near sitting position and then fall back to the reclining position in the bed.
