Abstract: Social networking in a virtual space over a network is facilitated. Subscriber computing devices each operated by a subscriber are associated with a subscriber identifier. Each computing device is connected to the network. A subscriber profile is created in a profile datastore, wherein the subscriber profile comprises information about the subscriber and wherein the subscriber profile is associated with the subscriber's subscriber identifier. Subscriber identifiers associated with subscribers who are logged in to a website are monitored. The website defines a virtual space and the logged-in subscribers are characterized as present in the virtual space. A web page is served to the computing devices of the present subscribers via the network. The web page of a first subscriber comprises a first subscriber icon associated with the first subscriber and subscriber icons of other present subscribers.

Abstract: The invention is directed to improved automatic dispenser apparatus for dispensing sheet material and the like without contact between a user and the dispenser. Proximity detection apparatus is provided to detect the presence of a user in a detection zone generated outside the dispenser. Control apparatus controls actuation of the dispenser in response to the detected user. Preferred forms of the proximity detector include a sensor and a signal detection circuit operatively connected to the sensor. The sensor includes conductors configured to have a capacitance and positioned such that the capacitance is changed by the presence of a user within the detection zone. The signal detection circuit detects the change in capacitance and is provided with an oscillator having a frequency which is affected by the sensor capacitance and a differential frequency discriminator which detects changes in the oscillator frequency.
