Title: Inverter power source control for high-frequency heater
Inventor: MIYAZAKI SHINOBU
IPC: H02M7/48
Filed: 2004-05-25
Abstract: An oscillation control signal generated in an inverter power source control circuit (12) includes: a reference voltage setting signal for approximating the current waveform of the AC output of the AC power source (1) to a sinusoidal wave by making the both sides of the waveform generate current according to the fluctuation of the PWM control signal; and a waveform shaping signal consisting of a peak portion adjustment signal of the sinusoidal waveform for approximating the waveform peak portion of the current waveform to a sinusoidal wave by subtraction. Accordingly, even if the PWM control signal fluctuates, it is possible to automatically improve the power factor of the power source circuit above a predetermined value by approximating the current waveform of the AC output of the AC power source to a sinusoidal wave, thereby improving the power source efficiency.

Title: Tubular patent foramen ovale (pfo) closure device with catch system
Inventor: CHANDUSZKO ANDRZEJ J
IPC: A61B17/12
Filed: 2004-07-14
Abstract: The present invention provides a device for occluding an anatomical aperture, such as an atrial septal defect (ASD) or a patent foramen ovale (PFO). The occluder (20) includes two sides connected by a central tube. The occluder is formed from a tube (25), which is cut to produce struts (32) in each side.  Upon the application of force, the struts deform into loops. The loops may be of various shapes, sizes, and configurations, and, in at least some embodiments, the loops have rounded peripheries. In some embodiments, at least one of the sides includes a tissue scaffold. The occluder further includes a catch system (131) that maintains its deployed state in vivo. When the occluder is deployed in vivo,the two sides are disposed on opposite sides of the septal tissue surrounding the aperture and the catch system is deployed so that the occluder exerts a compressive force on the septal tissue and closes the aperture.

Abstract: A cranial orthosis (10) is contoured to match the curvature of an infant's cranial vault (22) to provide protection against the acquisition of postural cranial deformities (F) as a result of the infant's sleeping in the supine position. The orthosis is a molded plastic appliance (10) in the form of a shell, headband or helmet having interior surfaces that are smoothly contoured to conform in shape to surface curvature of the occipital (24), temporal (26), parietal (28) and frontal (30) bone areas of a healthy human infant having normal cranium size, shape and symmetry. The cavity (44) of the orthosis (10) forms a protective pocket that is sized to provide a close, non-interfering fit of the conformed interior surfaces (42) in facing relation to the infant's cranial areas, thereby allowing the infant's head weight forces to spread substantially uniformly across one or more of the conformed interior surfaces while the infant is resting on a sleep surface in the supine position.

Abstract: A manual reset high temperature limit thermostat is provided. The manual reset lockout feature is provided by a lock rod that is outwardly transitioned upon actuation of the thermostat when the sensed temperature reaches its high level limit. A manual reset reset slide then engages the lock rod to prevent automatic resetting of the thermostat once the sensed temperature decreases below the thermostat set point. Resetting of the thermostat once the temperature has decreased may be accomplished by sliding the switch to disengage the reset slide from the locking rod. The thermostat internal snap action mechanism then retracts the lock rod and resets the thermostat's electrical contacts.

Title: Preventing network reset denial of service attacks
Inventor: DALAL MITESH
IPC: H04L12/24
Filed: 2005-01-05
Abstract: Approaches for preventing TCP RST attacks and TCP SYN attacks in packet-switched networks are disclosed. In one approach, upon receiving a TCP RST  packet, a first endpoint node challenges the second endpoint node in the then-current connection using an acknowledgement message. If the connection is genuinely closed, the second endpoint node responds with a RST packet carrying an expected next sequence value. The first endpoint node takes no action if no RST packet is received. Thus, attacks are thwarted because an attacker does not receive the acknowledgment message and therefore cannot provide the exact expected next sequence value.

Abstract: One or more cardiovascular parameters is estimated as a function of the arterial pressure waveform (P(t)), in particular, using at least one statistical moment (~2P, ~3P, and ~4P)of a discrete representation (P(k)) pressure waveform having an order greater than one. Arterial pressure may be measured invasively or non-invasively. Arterial compliance (K), an exponential pressure decay constant (tau),vascular resistance (R), cardiac output (CO), and stroke volume (SV) are examples of cardiovascular parameters that can be estimated using various aspects of the invention. In a single-moment embodiment of the invention, cardiac stroke volume (SV) of a subject is estimated as a function of a value derived from the pressure waveform. In a multi-moment embodiment of the invention, two or more of the first four moments - mean, standard deviation, skewness, and kurtosis - of the pressure waveform are used to estimate the cardiovascular parameter(s) of interest, as well as heart rate, statistical moments (~1T, ~2T, ~3T, ~4T) of a set of pressure-weighted time values (T(j)), and certain anthropometric patient measurements such as age, sex, body surface area, etc.
