Touchless Sensor for Physiological Monitor Device

A device for monitoring heart rate and blood oxygen levels using improved pulse oximetry sensors. Pulse oximetry sensors function in either transmission mode or reflectance mode. The device of the present invention provides improved sensors functioning in transmission mode to be useful on anatomical structures with dense tissue, such as the wrist. Additionally, a combination of sensors are used to enhance the performance of monitoring devices using pulse oximetry technology. By combining sensors that function in transmission mode and reflectance mode, quality and accuracy of the monitoring device is enhanced. The data from the sensors are communicated with a microcontroller for analyzing the data. More accurate data collection translates to more accurate analysis using formulas or algorithms. The resulting analysis is conveyed to the user through a display, either digitally or in color.

Catheter with cryogenic and heating ablation

A catheter includes a cryoablation tip with an electrically-driven ablation assembly for heating tissue. The cryoablation tip may be implemented with a cooling chamber through which a controllably injected coolant circulates to lower the tip temperature, and having an RF electrode at its distal end. The RF electrode may be operated to warm cryogenically-cooled tissue, or the coolant may be controlled to conductively cool the tissue in coordination with an RF treatment regimen, allowing greater versatility of operation and enhancing the lesion size, speed or placement of multi-lesion treatment or single lesion re-treatment cycles. In one embodiment a microwave energy source operates at a frequency to extend beyond the thermal conduction depth, or to penetrate the cryogenic ice ball and be absorbed in tissue beyond an ice boundary, thus extending the depth and / or width of a single treatment locus. In another embodiment, the cooling and the application of RF energy are both controlled to position the ablation region away from the surface contacted by the electrode, for example to leave surface tissue unharmed while ablating at depth or to provide an ablation band of greater uniformity with increasing depth. The driver or RF energy source may supply microwave energy at a frequency effective to penetrate the ice ball which develops on a cryocatheter, and different frequencies may be selected for preferential absorption in a layer of defined thickness at depth in the nearby tissue. The catheter may operate between 70 and minus 70 degrees Celsius for different tissue applications, such as angioplasty, cardiac ablation and tissue remodeling, and may preset the temperature of the tip or adjacent tissue, and otherwise overlay or delay the two different profiles to tailor the shape or position where ablation occurs or to speed up a treatment cycle.

Multimedia communications system and method for providing audio on demand to subscribers

An audio-on-demand communication system provides real-time playback of audio data transferred via telephone lines or other communication links. One or more audio servers include memory banks which store compressed audio data. At the request of a user at a subscriber PC, an audio server transmits the compressed audio data over the communication link to the subscriber PC. The subscriber PC receives and decompresses the transmitted audio data in less than real-time using only the processing power of the CPU within the subscriber PC. According to one aspect of the present invention, high quality audio data compressed according to lossless compression techniques is transmitted together with normal quality audio data. According to another aspect of the present invention, metadata, or extra data, such as text, captions, still images, etc., is transmitted with audio data and is simultaneously displayed with corresponding audio data. The audio-on-demand system also provides a table of contents indicating significant divisions in the audio clip to be played and allows the user immediate access to audio data at the listed divisions. According to a further aspect of the present invention, servers and subscriber PCs are dynamically allocated based upon geographic location to provide the highest possible quality in the communication link.

Tunable resonant leaky-mode N/MEMS elements and uses in optical devices

Mechanically tunable electromagnetic and photonic devices featuring enhanced spectral tunability with minimal mechanical movement are provided. These nano / micro-electromechanically (N / MEMS) tunable elements, including filters and pixels, rely on leaky-mode resonance effects in subwavelength photonic lattices that constitute periodic wavelengths. Such elements can operate in reflection (bandstop) or transmission (bandpass) modes, and can be arranged in one-dimensional or two-dimensional arrays, or operated as single units, and their spectral regions are controlled by the element design. Input electromagnetic radiation illuminates the element and is then filtered, modulated, analyzed or tuned by the element. Mechanical motion alters the structural symmetry, and therefore, the tuning properties, of the nanostructured subwavelength resonance elements. Further, incorporating metals and dielectrics to generate coexisting plasmonic and leaky-mode resonance effects adds to the versatility of the potential applications.

Method forversatile content control

The owner of proprietor interest is in a better position to control access to the encrypted content in the medium if the encryption-decryption key is stored in the medium itself and substantially inaccessible to external devices. Only those host devices with the proper credentials are able to access the key. An access policy may be stored which grants different permissions (e.g. to different authorized entities) for accessing data stored in the medium. A system incorporating a combination of the two above features is particularly advantageous. On the one hand, the content owner or proprietor has the ability to control access to the content by using keys that are substantially inaccessible to external devices and at the same time has the ability to grant different permissions for accessing content in the medium. Thus, even where external devices gain access, their access may still be subject to the different permissions set by the content owner or proprietor recorded in the storage medium. When implemented in a flash memory, the above features result in a particularly useful medium for content protection. Many storage devices are not aware of file systems while many computer host devices read and write data in the form of files. The host device provides a key reference or ID, while the memory system generates a key value in response which is associated with the key ID, which is used as the handle through which the memory retains complete and exclusive control over the generation and use of the key value for cryptographic processes, while the host retains control of files.

Footwear component system

A shoe has a sandal and a removable bootie. The sandal is provided with at least one adjustable strap for securing the sandal about a wearer's foot and includes an outsole. The removable bootie is adapted to cover the wearer's foot and includes a sole, the removable bootie may be provided with an attachment system such as laces or straps for securing the bootie about the foot. The sandal and the bootie are configured to cooperate with each other so that when the bootie is inserted into the sandal and secured therein, the sandal and bootie combination results in the shoe, and wherein the sandal and the bootie can be worn independently of each other.
