Abstract: Embodiments disclosed herein enable a user of a client device to interact with an animated image. A client device obtains first and second animated image files associated with one another. The client device displays sequentially in a loop, via a display thereof, frames of the first animated image file to provide for a first illusion of motion. While any one of the frames of the first animated image file is being displayed in the loop, the client device detects a user selecting a location on the display within a region of the display where the frames of the first animated image file are being displayed sequentially in the loop, and in response thereto, transitions to displaying frames of the second animated image file, and thereby transitions from providing the first illusion of motion to providing a second illusion of motion.

Abstract: Methods and systems for enabling a client device to display interactive animated images are disclosed. A client device sends a query including a unique identifier to a server system. A response to the query includes first and second addresses specifying where respective first and second animated image files associated with the unique identifier are stored. The client device downloads first and second image files using the first and second addresses. The client device displays sequentially a first plurality of frames of the first animated image file downloaded using the first address. In response to detecting a user interacting with a user interface of the client device in a predetermined manner (e.g., tapping a screen) while the first plurality of frames are being displayed, the client device transitions to displaying a second plurality of frames of the second animated image file downloaded using the second address.

Abstract: Embodiments of the present technology enable messages including both standard and custom characters to be communicated between client devices. Each of the standard character(s) is included within a Unicode Standard that is supported by an operating system of a client device. By contrast, each of the custom character(s) is not included within the Unicode Standard. Such embodiments enable users to create their own custom characters, such as custom emoji, or utilize custom characters created others. Beneficially, embodiments described herein overcome many of the drawbacks associated with electronic messages being limited to including only standard characters, such as standard emoji.

Abstract: Embodiments described herein enable messaging using custom characters (e.g., custom emoji) that are not part of a Unicode Standard, as well as associating such custom characters with embedded content. The embedded content can be, for example, a quick response (QR) code, a coupon, an advertisement, a map, a static image, a moving image, a video, audio, or combinations thereof. A client device receives message data including a unique custom character reference. The client device obtains (e.g., from a remote server) image data and embedded data for the custom character associated with the unique custom character reference. The client device uses the image data to display the custom character associated with the unique custom character reference. The client device displays embedded content associated with the custom character, in response to accepting an indication that a user of the client device has selected the displayed custom character.

Abstract: A system and method for transmitting a radio frequency (RF) signal in a RF bandwidth over a low bandwidth medium, e.g., in-building cabling, which has a transmission bandwidth below the RF bandwidth. The system has a unit for intercepting the RF signal and a global reference oscillator for distributing a global reference tone of high stability to the entire system. Local oscillators are controlled by adjustment signals derived from this global reference tone to deliver RF reference tones of high stability required for mixing the RF signal to obtain an intermediate frequency (IF) signal which is fed through the low bandwidth medium. The global reference tone is preferably delivered through the same low bandwidth medium to desired locations, such as remote coverage sites in a network for cellular communications, cordless telephony, local RF communications, interactive multi-media video, high bit-rate local communications.

Abstract: A system and method is disclosed for distributing a radio frequency (RF) signal within a building structure or other structure not readily transparent to radio frequencies. The RF signal originates at a wireless local loop (WLL) base station and is intercepted by a main antenna on the building structure. The intercepted RF signal, which is contained in a RF bandwidth, is distributed throughout the building structure over a low bandwidth medium, e.g., in-building cabling, which has a transmission bandwidth below the RF bandwidth. In order to accomplish this, the system has a global reference oscillator for distributing a global reference tone of high stability to the entire system. Local oscillators controlled by this global reference tone deliver RF reference tones of high stability required for mixing the RF signal to obtain an intermediate frequency (IF) signal which is fed through the low bandwidth medium to remote sites.

Abstract: A system and method for transmitting a radio frequency (RF) signal in a RF bandwidth over a low bandwidth medium, e.g., in-building unshielded twisted pair (UTP) cabling, which has a transmission bandwidth below the RF bandwidth. The system has a unit for receiving the RF signal and a global reference oscillator for distributing a global reference tone of high stability to the entire system. Local oscillators controlled by this global reference tone deliver RF reference tones of high stability required for mixing the RF signal to obtain an intermediate frequency (IF) signal which is fed through the low bandwidth medium to remote sites. A 10 base T cable network, often pre-existing in many building structures, provides a suitable, cost effective low bandwidth medium for such RF communication. Two of the four twisted pair cables of a UTP cable are sufficient to support bi-directional communication.

Abstract: Individual channels are centrally and tunably selected for emission in a distributed wireless communications system. A high-frequency signal received at a central antenna is down-converted such that a selected channel corresponds to a predetermined frequency range. Non-selected channels are filtered out. The selected channel is transmitted to remote locations over commonly available transmission lines, up-converted, and re-emitted. The transmitted channel is chosen by tuning the frequency of the local oscillator used for down-conversion. A high-stability global tuning signal is used to tune and stabilize the local oscillators used for up-conversion. The global tuning signal is generated by frequency-dividing the down-conversion local oscillator signal by a fixed number, while the up-conversion local oscillator signals are generated by frequency-multiplying the global tuning signal by the same fixed number. Phase-locked loops are used for frequency multiplication and stabilization.

Abstract: The placement of repeater or base station antennas in an in-building or urban wireless RF communications network is optimized using field measurements. Test antennas are placed at a number of sites within the coverage area, and the signal from each test antenna is measured at different locations within the coverage area. The measurement allows the simulation of the coverage provided by different arrangements of antennas. An optimum arrangement can then be chosen. The optimum arrangement of antennas is chosen by maximizing a utility function that depends on the quality of the coverage within the area and on the cost of installing an arrangement. A database of architectural categories (building plans) and measurement results for each category is built by a method of the present invention. A new building is then matched to the closest component categories in the database, thus allowing the optimization of coverage in a coverage area without the measurement of signals from nest antennas in the new building.

Abstract: An active pull up arrangement coupled to a high voltage source generates an operating voltage. An amplifier for a dynamic focus modulating signal is energized by the operating voltage and has a plurality of transistors, for example low voltage transistors, coupled as Darlington pairs in a differential configuration. One of the low voltage transistors is coupled in series between a resistor in the pull up arrangement and a return supply, for example ground, in a push pull configuration. A fault condition in the push pull configuration can destroy the resistor and cause an open circuit condition. A switch, for example a diode or a Zener diode, is coupled between the one transistor of the amplifier and the supply return. The switch prevents reverse breakdown of the transistors in the event of the fault condition, until the resistor is destroyed. The resistor may be a fusible resistor.
