Abstract: Apparatuses and associated methods of manufacturing are described that provide a particulate protective article. An example particulate protective article includes one or more structural sections that are formed of a primary material and one or more protective sections connected with the one or more structural sections so as to form an article of clothing. Each protective section is formed of a particulate blocking or filtering material. In an instance in which the article is worn by a user, the one or more protective sections shield one or more corresponding areas of the user's superficial lymphatic system from particulate matter. In some embodiments, the article is formed as a shirt so as to shield the torso, armpits, and/or neck of the user. In other embodiments, the article is formed as an undergarment so as to shield the groin, lower abdomen, and/or buttocks of the user.

Abstract: A line knot tying apparatus and method of use is disclosed that assists in joining first and second line free end portions. The knot tying apparatus includes a housing with an aperture therethrough that is slidably engaged to an extension element wherein an element biases the extension to a closed state that can be manually pushed into an open state. Also a helical coil with continuously increasing pitch line distance is attached to the housing. Operationally the first and second line free end portions each have a manual removable slidable engagement to the helical coil with opposing free ends that are wound in a plurality of loops about the opposing line then being secured by the extension element in the closed state. Then manually pulling the non free end line portions apart from one another to form the knot, further releasing the opposing line free ends from the extension element.

Abstract: An audio processing device including multiple input receivers to receive input signals from multiple sources and a user interface that facilitates selection of audio source and associated parameters, amplification and processing of the chosen source or sources and an audio output, operably coupled to wired or wireless earphone, headset, or headphone to the end user. The enhanced user interface provided by a smartphone, or tablet device or other interface the user can choose one or more audio sources to be heard and enhanced with additional content or audio sources from a network or other secondary signal source.

Abstract: A hybrid energy system heats or cools a plant with a geothermal unit powered at least partly by a fuel cell, which may also power other devices. The thermal fluid for the geothermal unit also cools the fuel cell via a heat exchanger. A digital controller bypasses a variable portion of the thermal fluid around the heat exchanger to regulate the fuel-cell temperature.

Abstract: A rule based routing system and method is disclosed. The rule based routing system and method matches employee skills with a customer profile thereby facilitating improved customer service and identifying cross-sell opportunities. The rule based routing system and method identifies a call profile for the call, matches the call profile to 3 sales and service resource profile representing an identified resource, generates an instruction signal and routes the call to the identified resource in response to the instruction signal. The virtual sales and service center is monitored for overflow or overload conditions and load balancing and overflow rules are applied to the call in response to detection of overflow or overload conditions. The customer profile includes a language type, a customer type, a business segment identifier, a request type and a product associated with the customer.
