摘要:
Systems and methods for exposing fluids and other materials that may contain biohazards to ultraviolet radiation are provided. One system for exposing a fluid includes a baffled conduit for conveying the fluid so that the fluid flow and its exposure to ultraviolet radiation is rendered more uniform. Other systems include feedback for determining when to replace light sources and filters and to ensure proper biodosimetry. Additional methods and systems for exposing fluids and other materials that may contain biohazards are also provided.

Methods and apparatus for ultraviolet sterilization are provided. The apparatus can include a housing having an opening through which objects can be inserted for sterilization, a killing chamber having an inner surface that is substantially reflective at ultraviolet wavelengths; and at least one ultraviolet radiation source inside the housing. The methods and apparatus are well suited for medical tools, dental tools, body art tools, and baby feeding related objects.
摘要:
A method for disseminating emergency notification content from an emergency originating source. The method comprising: delivering the emergency notification content from the emergency originating source to at least one transmitting party; selecting a subset of users from among a set of users for dissemination of the emergency notification content based on the subject matter of the emergency notification content; and delivering the emergency notification content from the at least one transmitting party to a device corresponding to each user from the selected subset of users.
摘要:
A method is provided for making the storage media having data stored thereon. In one aspect of the making of storage media, a first layer is formed, where the first layer is substantially transparent to a predetermined first radiant energy used for reading the data. Next, a second layer is formed on the first layer, which is substantially opaque to the first radiant energy. Finally, a pattern is formed that comprises a plurality of holes in the second layer, where each of the holes have a largest dimension which is greater than a wavelength of the first radiant energy, and the data is stored as the presence or absence of a hole in the pattern.

A storage media for storage of data thereon is provided. The storage media including: a first layer, the first layer being substantially transparent to a predetermined radiant energy used for reading the data; and a second layer formed on the first layer and being substantially opaque to the radiant energy, the second layer having a pattern comprising a plurality of holes, each of the holes having a largest dimension which is greater than a wavelength of the radiant energy, the data being stored as the presence or absence of a hole in the pattern. Also provided are a method for fabricating the storage media as well as an apparatus and method for reading the data stored on the storage media.
摘要:
In an air sterilization system that includes a UV kill chamber for sterilizing air that is to be supplied to users, the effectiveness of killing or neutralizing pathogens is increased by including not only a UV light source of a certain intensity but also including a particle filter and providing short duration high intensity UV radiation. In the case of a user specific system that includes a face mask to supply air to a specific user, exhaled air from the face mask may be sterilized as well, either by using the same kill chamber or by using a separate kill chamber.
摘要:
A portable sterilization apparatus that includes a face mask connected to a kill chamber having an ultraviolet source to destroy biological contaminants such as viruses, bacteria and fungi in air supplied to the mask, further includes a disposable particle filter in the kill chamber for filtering out particulates prior to irradiating the air with UV light, and in the case of a mercury vapor lamp UV source, a quartz sleeve surrounding the lamp. Valves are included in the face mask to limit carbon dioxide exhalation back into the kill chamber and to facilitate exhalation of air to the atmosphere.
摘要:
The invention relates to video distribution systems and, more particularly, to a system that blanket transmits video/audio content such as movies (for example, via satellite downlink transmission) to each customer's computer-based recording, storage and playback system. Customers preselect from a list of available movies or other content in advance using an interactive screen selector, and pay for only the video/audio content that is actually viewed.
摘要:
Merchants directly access a network of thousands of large, high resolution electronic billboard displays and directly send their own advertisements electronically to the network to be displayed at locations and times they select. The advertisements include order numbers that may be used by consumers to order the advertised products and product information through a universal, automated order processing system that represents many merchants.
