Abstract: The present disclosure concerns mesoporous silica nanoparticles (MSNP) functionalized to cross in and out of cells and loaded with one or more therapeutics to provide a vehicle that can effectively provide localized treatment to both intracellular and extracellular space. The MSNPs provide a vehicle for adjunct treatment of periodontitis, being able to provide treatment against the microbes and to the tissue.

Abstract: A method is proposed to induce the sensation of movement in subjects in flight simulators and in cosmonauts, creating a cognitive simulation of movement through the Vestibular Electrical Stimulation. The system consists of a control unit, a function generator and a power amplifier. The device injects electric current over the mastoid process (galvanic vestibular stimulation), capable of activating the neurons of the vestibular system and inducing a movement sensation, in coordination with a flight simulation program or subject's movement in the simulator. The use of the device modifies eye movement control responses, electrically activating the vestibular-ocular, vestibulo-colic and vestibule-spinal reflexes. The main purpose of this device is to provide sensory input to enhance the experience in pilots during flight training or in microgravity.

Abstract: An integrated circuit that can include a driver having a first driver output, and a first resistance coupled between a first node coupled to the first driver output and a second node. The first resistance can include a process resistor including a first material having a first temperature coefficient, and an interconnect resistor configured to provide at least 20% of the first resistance and including a second material having a second temperature coefficient which changes resistance in an opposite direction with temperature as compared to the first temperature coefficient. A first terminal of the interconnect resistor is directly connected to a first terminal of the process resistor.

Abstract: A temperature sensor configured to, after a predetermined number of stop counting assertions, determine the temperature dependent voltage and thus the temperature at the output of a counter. During a calibration phase, when a counter value is not equal to a test counter value in a pulse generator circuit, capacitance of the temperature sensor is adjusted until the counter value is equal to the test counter value.

Abstract: A cooktop, having at least one burner and at least one control. Each burner may be associated with a particular control. A burner sensor detects the presence of a pot on the burner. When a pot is detected, an illuminated path is activated between the burner and its associated control. A control sensor detects a user's proximity to the control. When a user is detected, the illuminated path is also activated. Alternatively, a lighting effect is used to highlight the associated burner and control. Alternatively, each burner is associated with a burner selector button or burner user selection interface, and a controller is used to adjust the parameters of a burner selected using the burner selector button. A communication link may be provided between the cooktop and a hood, and a display provided on the hood to indicate burner status, as well as other settings such as timer progress.

Abstract: A circuit and method for regulating an output voltage are provided. The circuit includes a fully differential first stage amplifier, a second stage amplifier, and a power output driver transistor. The first stage amplifier receives a reference voltage and feedback voltage relative to an output voltage of the power output driver transistor. A differential output of the first stage amplifier is received at differential inputs of the second stage amplifier. The second stage amplifier provides a voltage at a control terminal of the power transistor. The output voltage of the power transistor is based on the voltage at the control terminal and a supply voltage coupled to the power output driver transistor.

Abstract: Embodiments of the present invention relate generally to digital volume control in digital audio systems. One embodiment relates to a digital audio system having a digital audio processor and a digital volume control coupled to the digital audio processor. The digital volume control includes a feedback loop having an attenuator, and error determination unit, and a filter. The feedback loop determines the attenuation error and shifts the attenuation error beyond a predetermined digital audio range. The output of the digital volume control maintains a substantially constant SNR and THD with respect to the level attenuation over the predetermined digital audio range.

Abstract: A damping tape comprising: (a) a backing comprising a thermoplastic film having front and rear major surfaces; and (b) a sheet of resilient fibers having anchor portions bonded to the film at bonding locations spaced along the front surface of the backing, and arcuate portions projecting from the front surface of backing between the bonding locations, the lengths of some of the fibers in the sheet may be disposed in various different directions with respect to each other; and (c) a layer of adhesive covering significant portions of the rear surface of the backing. The tape may further comprise optional release liner over the adhesive layer. In some embodiments, the sheet of fibers may be covered with an overcoat layer.
