Abstract: An amplifier for signal amplification, the amplifier comprising: a signal input arrangement; a signal output arrangement; a first transistor (Q1); a second transistor (Q2); and a third transistor (Q3), wherein: the first (Q1), second (Q2) and third (Q3) transistors are coupled to one another to form a transconductance cell, the transconductance cell is coupled to the signal input arrangement and the signal output arrangement, and the transconductance cell is operable to receive a first signal from the signal input arrangement, amplify the first signal and output an amplified first signal to the signal output arrangement. There is also disclosed a receiver incorporating the amplifier and methods of operating the amplifier.

Abstract: Described herein is a power-efficient Gm-C filter, wherein the Gm-C filter includes several operational transconductance amplifiers (OTAs). In an example, at least two of the OTAs share a common bias current. Further, output of one of the OTAs is used to bias another one of the OTAs. Also described herein is a power-efficient clock generator circuit that is configured to output non-overlapping clock signals. The clock generator circuit includes a ring oscillator circuit, which includes several inverter stages. The clock generator circuit is well-suited for controlling operation of switches.

Abstract: A bypass pruning tool with a manual dial adjustment for varying the degree of blade and handle opening. A rotary drum dial uses a nautilus cam with a shaft cam-follower to provide adjustment of the blade and handle openings in a continuous range. A blade locking mechanism provides position closure of the blades.

Abstract: Described herein are various technologies relating to processing a coherent signal. A receiver is configured to receive an analog signal, and process the analog signal to generate an input analog signal. The input analog signal has been modulated according to a suitable modulation sequence. A coherent signal sampler coherently samples the modulation sequence, and the result of such sampling is in turn used to demodulate the input analog signal. The resultant signal is then passed to a sigma delta modulator, where it is converted to digital form.

Abstract: A mobile communication device identifies and selects a wireless local area network (WLAN) available for communications in its coverage area. Automatically, without detecting any requests made by a user via a browser application.. The mobile device initiates a request (e.g. an HTTP GET request) to a predetermined server site of a communication network which is outside of the WLAN. In response to initiating the request, the mobile device receives a response message via the WLAN and identifies, from the response message, whether the request to the predetermined server site has been redirected to a redirect server site. The WLAN may be a WLAN “hotspot,” where the redirect server site is a login server. The identifying may be performed by comparing content from the response message to predetermined content of the predetermined server site. In response to identifying that the request has been redirected, the mobile device causes an indication to be produced at its user interface.

Abstract: A system, device and method are described for operating a communication device communicating with a wireless network. The method comprises in a power save mode wherein a communication subsystem of the communication device has been deactivated: for a first period beginning at a first instance, re-activating the subsystem, executing an action relating to a link layer connection condition, and then de-activating the subsystem; and for a second period beginning at a second instance, re-activating the subsystem, executing an action relating to a network layer connection condition, and then de-activating the subsystem. For the method, the first period is repeated on a cycle based on a first frequency timed to allow the communication device to process a beacon signal from the wireless network; and the second period is repeated on a cycle based on a second frequency of occurrence of an Address Resolution Protocol request in the wireless network.

Abstract: The invention provides a method for verifying the age of an animal providing meat using volatile profiles that comprises the step of providing a sample of animal meat. The method uses one or more chemical analyses to obtain a profile of a set of volatile organic compounds from a sample of meat from an animal. The profile is fit to a mathematically discriminating function resulting. The data obtained is analyzed in order to establish a correlation between the age of the animal (tooth development) and volatiles exuded by meat.

Abstract: A system and method for authenticating a peer device onto a network using Extensible Authentication Protocol (EAP). The key lifetime associated with the keying material generated in the peer device and the authentication server is communicated from the authenticator to the peer device within the EAP Success message. The peer device, having been provided with the key lifetime, can anticipate the termination of its authenticated session and initiate re-authentication prior to expiry of the key lifetime.
