34 results about "Safety case" patented technology

A Safety Case is a structured argument, supported by evidence, intended to justify that a system is acceptably safe for a specific application in a specific operating environment. Safety cases are often required as part of a regulatory process, a certificate of safety being granted only when the regulator is satisfied by the argument presented in a safety case. Industries regulated in this way include transportation (such as aviation, the automotive industry and railways) and medical devices. As such there are strong parallels with the formal evaluation of risk used to prepare a Risk Assessment, although the result will be case specific. A vehicle safety case may show it to be acceptably safe to be driven on a road, but conclude that it may be unsuited to driving on rough ground, or with an off-center load for example, if there would then be a greater risk of danger e.g. a loss of control or an injury to the occupant. The information used to compile the safety case may then formally guarantee further specifications, such as maximum safe speeds, permitted safe loads, or any other operational parameter. A safety case should be revisited when an existing product is to be re-purposed in a new way, if this extends beyond the scope of the original assessment.

Hi Performance Security Folio for Digital Mobile Devices

This hi performance invention is related to products that consumer invests in and depend for their livelihood, communication and daily existence—the digital devices. Specifically Apple products. Adding to the equation mobility as the new generations lifestyle—and it is clear that this invention is long overdue. This invention is a consumer friendly product, of distinguished aesthetics, a hi performance product with superior performance in I mechanical (A Shield) and RFID/EMF shielding qualities (E-Shield)
Apple alone has 588 million users worldwide, each one owns min of 2 devices (1.7 average), 168 Million users in the US only, A large percentage of these consumers spend time in transit—while they carry with them all their priced tools—smart phone, Mac-Air Book, MacBook-Pro, iPad . . . etc. Each consumer spends an average of $1,500-$2,000 for these smart devices. While in transit—each one of them is vulnerable to physical damage and hacking.
This dual Hi Performance Invention relates to this segment of the consumers, who need full hi performance security cases for their mobile devices (hardware/A Shield) and in digital (software—E-Shield) sense. All these qualities in one simple and sophisticated product to serve both the hardware and the software to match the value of the device it is intended to house. Final result the device extends its normal life as it is designed to do.
The impending ubiquity of RFID tags poses a potentially widespread threat to consumer privacy. Selective blocking of RFID tags for consumer privacy is paramount today. This invention fulfill to the need today's consumer of hi performance, hi shield portfolio (folio) cases for their mobile devices for their hardware and their software, that is friendly, easy to use and difficult to destroy under normal circumstances. Private information is accessibility and vulnerable to remote reading by means of new technology. The synthesis of dual protection in one simple and sophisticated product, the object of this invention. The A Shield layer—a quadruple lamination layer, and the E-Shield Silver Plated lamination layers.
Selective blocking of RFID tags for consumer privacy is a must. The impending ubiquity of RFID tags poses a potentially widespread threat to consumer privacy. The simplest RFID tag will broadcast its ID serial number—that is, its electronic product code (EPC)—to any nearby reader. The ID number. It contains not only the traditional information contained in a printed barcode (indicating manufacturer and product type), but also a unique serial number for that tag. Each consumer product or item of clothing will be uniquely identified. And yet—we offer the consumer the option to tune out—to select when to have this information open to all readers I the vicinity. Relying at that to intelligent encryption, until the device gets enclosed in the “quiet” zone. WIFI—RFID EMF complete blocking. An elegant folio with ‘faraday cage’ effect upon consumers choice
Here is where Hi Performance Security Folio steps in. The E-Shield solution—comes from a variety of specialty silver plated materials, tested for hi shielding and conductivity performance. These are integrated in the shell of the folio for ultimate shielding protection from privacy intrusion (hacking). A variety of certified and tested materials like Silver Plated Conductive Silk and Silver Plated Nylon, both high surface conductivity and the best shielding performance, Incorporates the impact resistance lamination on the interior against accidental drop, and adds to that a tactile and soft to the touch shell due to the high quality of the material in which the shell is clad.]
A-Shield (exterior) is achieved by materials that are to be cast in this organic design in a variety of formula comprising 2-3 different material—from polyurethane, polycarbonate to metal sheet, aluminum, etc (9PG06 FIG. 38. FIG. 39,) all clad In tactile, soft to the touch man made materials while preserving the protective qualities inside the folio. The materials of the product and the dimensions scale vary—but the proportions and the purpose stay identical.
The overall Design is inherent in the purpose of the Folio—hi performance and hi Shielding the contents from physical damage and unwanted privacy intrusion. The purity of intent is presented in the high aesthetics of shape and in its high performance utility. This highly aesthetic organic form—is recognized as our signature. This organically designed elegant folio case, moderated physical damage from impact of the exterior, also reducing surface wear and tear, (the A-Shield) while providing full protection form undesirable privacy intrusion by the E-Shield Performance Layers.
