Abstract: A filtering power divider includes a first partial transmission line having a first electrical length, a second partial transmission line having a second electrical length, and a third partial transmission line having the second electrical length. The first, second, and third partial transmission lines connect to form a T-junction, and a sum of the first and second electrical lengths is ninety degrees. Thus, the first and second partial transmission lines cooperate to act as a quarter-wave transmission line. Similarly, the first and third partial transmission lines cooperate to act as a quarter-wave transmission line. Additional transmission lines may be connected to the first, second, and third partial transmission lines to implement a filter between an input port and each of two output ports.

Abstract: An eyebrow cover has a primary layer, an adhesive layer, an adhesive release liner, and a top release liner. The primary layer may be flexible so as to conform to an eyebrow and the structure of a user's face. The primary layer may be shaped so as to surround the eyebrow, minimizing excess coverage on the face while protecting the microblading procedure. Further, the adhesive layer may surround a non-adhesive portion of a lower surface of the primary layer. To protect the eyebrow cover, the adhesive release liner may releasably adhere to the adhesive layer.

Abstract: A system for cutting marine grasses, weeds and other plant life to protect a propeller drive watercraft is disclosed. An adjustable, protective cutting edge to protect a propeller, drive shaft of a boat or other watercraft motor is further disclosed. A propeller protection device to mount upon a watercraft is further disclosed for optimizing the navigation of watercraft and reducing in-piloting maintenance of clearing plant matter from a propeller of a watercraft.

Abstract: A method for notifying users of an online social network of an activity performed within a web site that is external to the online social network by an individual who is a registered user of the online social network and the web site. The method comprises the steps of receiving a notification package from the external web site, the notification package including a notification message that describes the activity performed, parsing the notification package to extract a list of recipients, each of whom is to receive the notification message, and issuing the notification message to each of the recipients.

Abstract: A system for simulating in situ drilling and treatment conditions on a core sample from a subterranean formation. The system re-creates various subterranean loads and temperatures on a test sample representative of actual in situ conditions from the particular formation while a test structure within the system performs drilling activities on the core sample using drilling and treating under evaluation for use in the particular subterranean formation. Thus, the impact on selected drilling and treating fluids can be evaluated as well as the impact those fluids had on a sample from the subterranean formation under in situ conditions.

Abstract: An apparatus, comprising a biometric fingerprint identification sensor, the biometric fingerprint identification sensor configured to receive an input from a user, the input corresponding to a-predetermined factor, the predetermined factor comprising a force applied by a finger of the user to the biometric fingerprint identification sensor. A connected computer processor determines a qualitative or quantitative threshold based on the predetermined factor, receive the input from the fingerprint identification sensor, calculate a value of a variable associated with the predetermined factor and the input, and trigger a feedback output when the value approaches the threshold within a margin. A connected haptic feedback is device configured to provide haptic feedback to the body of the user when the haptic feedback device receives the triggered feedback output from the computer processor indicating the value is within the margin of the predetermined threshold.

Abstract: Techniques and systems for robotic aquaculture are described. In one embodiment, for example, a mariculture system may include an aquatic animal containment system operative to hold a population of aquatic animals, the aquatic animal containment system comprising an enclosed hull having a receptacle configured to receive a mechanical core, the mechanical core configured to store at least one sub-system to implement at least one function of mariculture system, and a position management system operative to maintain the enclosed hull at a depth below a surface of a body of water. Other embodiments are described.

Abstract: A method of processing a handover request from a base station controller (BSC) of a GSM (Global System for Mobile communication)-type network. The method comprises the steps of passing a handover request with GSM-type parameters from a base station controller (BSC) through a Master Switching Center (MSC) of the GSM-type network to a UMTS core network (CN) and to a Radio Network Controller (RNC) of the UMTS (Universal Mobile Telecommunications System) network, translating the GSM-type parameters to UTRAN parameters in the Radio Network Controller (RNC), and allocating UTRAN resources in response to the translated parameters.
