Abstract: In an exemplary embodiment, this system is found within a kitchen hood, such as those found in restaurants, used to remove excess cooking heat and grease. Building fire safety and sanitation codes mandate routine hood maintenance to maintain fire safety, operator comfort and workplace sanitation. Conventional maintenance can be very messy, time consuming and quite expensive. In an exemplary embodiment, the hood is fabricated to incorporate an integral heat exchanger which further creates a trough housing a grease extraction device. The exchanger and trough are located in such a manner that collected heat and/or grease may be removed from the exhaust air stream and further fabricated to permit automatic and/or semi automatic cleaning of both devices and trough. This invention improves fire safety and sanitation, saves time and reduces maintenance costs. Cleaning is achieved using less energy and keeps the heat exchanger at peak efficiency to further enhance energy savings.

Abstract: While performing prostate brachytherapy in which radioactive seeds are implanted into the prostate, both X-ray and transrectal ultrasound (TRUS) data are collected. The X-ray data indicate all of the implanted seeds, but not their relative position within the prostate. The TRUS data correspond to both axial and longitudinal ultrasound images. A subset of the implanted seeds can be automatically (or manually) detected in the TRUS data (using longitudinal ultrasound images), and the prostate is indicated in the TRUS data (using axial ultrasound images). Registration is performed between the X-ray and TRUS data, thereby identifying the disposition of all implanted seeds within the prostate, enabling dosimetry to be intraoperatively determined. A medical practitioner can thus determine whether and where to implant additional seeds to achieve a desired optimal dosage and do so before the prostate brachytherapy procedure is concluded.

Abstract: The present invention uses a releasable locking tube to integrate, anchor and bind supplemental hair ventilated on a polyurethane strip to strands of naturally growing hair. Rectangular strips of double-sided tape add extra security to the hair attachment to prevent slippage. Together both the locking tubes and the double-sided adhesive strips create a bi-locking system for securing the supplemental hair to the individuals' naturally growing hair for a prolonged period of time. The locking tubes can be easily removed without damaging the naturally growing hair. By loosening the locking tubes on the naturally growing hair, the position of the tubes can be adjusted closer to the scalp to compensate for growth of the naturally growing hair away from the scalp. Thus, the extension can be easily adjusted closer to the scalp every few weeks.
