An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.

An flow meter includes a coupler, a support member, an image sensor, and one or more processors. The coupler is adapted to couple to a drip chamber. The support member is operatively coupled to the coupler. The image sensor has a field of view and is operatively coupled to the support member. The image sensor is positioned to view the drip chamber within its field of view. The one or more processors are operatively coupled to the image sensor to receive data thereform. The one or more processors (1) receive image data from the image sensor, and (2) determine an existence of a free flow condition by identifying an optical distortion of an area behind the free flow condition within the drip chamber using the received image data.

A flow meter includes an image sensor and a processor. The image sensor is configured to capture an image of a drip chamber. The processor is configured to determine whether the captured image of the drip chamber contains a match to a template, and to apply a blurring function to the image captured by the image sensor of the drip chamber such that the processor can determine if the captured image contains a match to the template.

A heat recovery system comprising: an LNG warmer; at least one item of equipment requiring cooling and thereby generating waste heat; a heat exchanger arranged to provide heat exchange between the LNG warmer and the waste heat, whereby said waste heat can be used to provide warming for the LNG; wherein said heat exchanger is a closed loop heat exchange means, whereby the heat exchange fluids in said heat exchanger are substantially retained within the heat exchanger during operation of the system. This enables the system to be operated offshore without needing to use the surrounding seawater to provide cooling for the waste heat from the equipment.

In the manufacture of semiconductor packages having molded plastic bodies, the plating of all of the surfaces of the molding tool that comes into contact with the molten resin during molding with a nodular thin dense chromium ("NTDC") coating prevents the surfaces from adhering to the package body and ensures good package release, without formation of cracks or craters in the package body. This, in turn, permits the amount of both release agents and adhesion promoters used in the molding compound to be substantially reduced, or eliminated altogether, thereby resulting in a package body having improved strength and adhesion with the components of the package, and hence, an improved resistance of the package body to the propagation of cracks and its subsequent penetration by moisture.

The invention relates to anode exhaust gas treatment methods for solid oxide fuel cell power plants with CO2 capture, in which the unreacted fuel in the anode exhaust (301) is recovered and recycled, while the resulting exhaust stream (303) consists of highly concentrated CO2. It is essential to the invention that the anode fuel gas (102) and the cathode air (205) are kept separate throughout the solid oxide fuel cell stacks (1). A gas turbine (202,207) is included on the air side in order to maximise the electrical efficiency.

A match and destroy (MaDe) technique for filtering spam mail assigns at least two email addresses per user when the user first registers for an email account or when the MaDe software is installed on the server. The first email address is designated as the “True address,” and the user is made aware of only this address. The second email address is designated as the “Trap address,” and the user is not made aware of this address. Spammers send spam mail to all available email addresses as a spammer is unable to differentiate a True address from a Trap address. A MaDe filter is provided that detects when the same email is received in both the True and the Trap(s) inboxes. When this duplicate receipt occurs, the filter informs the resident spam filters that the email is a spam candidate.

An improved method and apparatus is provided as a system to enhance skin appearance and health, in which skin is cleaned (or exfoliated) and conditioned by use of microelements affixed to a base element or hand-held patch. The dimensions of the microelements are controlled so as to remove a certain number of layers of skin cells and to accumulate those skin cells, along with other foreign substances, into areas between the microelements. In addition, a conditioning compound or therapeutic active can be applied to the exfoliated skin to enhance the skin. Moreover, the amount of accumulated skin cells represents a self-limiting maximum quantity that cannot be substantially exceeded regardless of the number of attempts by a user to re-use the microstructure apparatus.

A system and method for maintaining positions of bones fixed or approximated relative to each other is provided that is ideal for minimizing interference with surrounding viscera in spinal column procedures, although other good application therefor are also disclosed. In the preferred form, a cable anchoring apparatus in the form of a screw member having an elongate shank that is threaded for substantially the full length thereof is employed. An internal driver surface is provided so that the size of the proximate end of the shank can be minimized or maintained consistently sized with respect to the reminder of the shank with no enlarged driver head formed thereat. This allows the amount of bone material that is removed from full insertion of the screw anchor to be minimized, i.e. no countersinking for an enlarged driver head is necessary, thus improving holding power of the cable anchor herein. Further, the full threading of the shank for substantially its entire length enables the screw member to be fully sunk into the bone so that no portions thereof, such as an enlarged screw head, project into the surrounding body cavity in which the bone is located. In the spinal column application, a criss-cross cable pattern is disclosed to better resist torsional forces and keep any decompression devices in place in the gap between adjacent vertebrae.
