Malicious network activities do not make use of the Domain Name System (DNS) protocol to reach remote targets outside a local network. This DNS-based enforcement system for confinement and detection of network malicious activities requires that every connection toward a resource located outside the local network is blocked by default by the local enforcement box, e.g. a firewall or a proxy. Outbound connections are allowed to leave the local network only when authorized directly by an entity called the DNS Gatekeeper.

There is provided an optical device, composed of a display source (4), an imaging optical module (8), a projection module (12) having a projection mechanism including an input aperture (10) and output aperture (14) defined by a surface area, and an exit pupil (16). The projection mechanism is non-uniform over the area of the output aperture (14).

There is provided an optical device including a light-transmitting substrate having at least two major surfaces and edges, optical means for coupling light into the substrate by total internal reflection and at least one partially reflecting surface located win the substrate.

Coding within noisy communications channels is essential but a theoretical maximum rate defines the rate at which information can be reliably transmitted on this noisy channel. Capacity-achieving codes with an explicit construction eluded researchers until polar codes were proposed. However, whilst asymptotically reaching channel capacity these require increasing code lengths, and hence increasingly complex hardware implementations. It would be beneficial to address architectures and decoding processes to reduce polar code decoder complexity both in terms of the number of processing elements required, but also the number of memory elements and the number of steps required to decode a codeword. Beneficially architectures and design methodologies established by the inventors address such issues whilst reducing overall complexity as well as providing methodologies for adjusting decoder design based upon requirements including, but not limited to, cost (e.g. through die area) and speed (e.g. through latency, number of cycles, number of elements etc).

A thin keypad including a top surface layer, a light guide layer, a capacitive sensing layer and a piezo layer provides for touch input, pressure input and haptic feedback.

There is provided an optical system, including a mechanical body (110), a light-transmitting substrate (20) having two major surfaces and edges, embedded in the mechanical body, an optical element (90) for coupling light into the substrate by total internal reflection and a plurality of partially reflecting surfaces (22) carried by the substrate, wherein the partially reflecting surfaces are parallel to each other and are not parallel to any of the edges of the substrate. The system also includes an image capturing device (112), a display source (4), and an image-processing unit (114). The image-capturing device (112) is connected via the image-processing unit (114) to the display source (4).

With explosive penetration of portable electronic devices (PEDs) recent focus into consumer EEG devices has been to bring advantages including localized wireless interfacing, portability, and a low-cost high-performance electronics platform to host the processing algorithms to bear. However, most development continues to focus on brain-controlled video games which are nearly identical to those created for earlier, more stationary consumer EEG devices and personal EEG is treated as of a novelty or toy. According to embodiments of the invention the inventors have established new technologies and solutions that address these limitations within the prior art and provide benefits including, but not limited to, global acquisition and storage of acquired EEG data and processed EEG data, development interfaces for expansion and re-analysis of acquired EEG data, integration to other non-EEG derived user data, and long-term user wearability.

A device including a display, a memory and a tap detector arranged to generate a detection signal upon detection of a tap command. The device is arranged to assume either an idle state, in which the display is inactive, or a second state, in which the display is active and displaying information stored in the memory. The device is arranged to transit from the idle state to the second state when a tap is detected i.e. upon generation of the detection signal.

A light guide (11; 101; 111) comprising first and second oppositely arranged faces, an in-coupling portion (13a-f) for in-coupling of light from a light-source (12a-f; 95a-f; 102; 106a-c; 112a-f), and an out-coupling portion (15a-f; 103; 113a-f) located adjacent to the in-coupling portion (13a-f). The out-coupling portion (15a-f; 103; 113a-f) is configured to out-couple a primary light beam having a direction of propagation directed from a position in the in-coupling portion (13a-f) with a lower out-coupling efficiency than a secondary light beam having a direction of propagation directed from a position in the light guide (11; 101; 111) outside the in-coupling portion (13a-f). In this manner, a good mixing of light in the light guide can be achieved without imposing any particular requirements on the collimation of the in-coupled light.

There is provided an optical device, having a light-transmitting substrate (20) having at least two major surfaces parallel to each other and edges; a display light source; optical means for coupling light from the light source into the substrate (20) by internal reflection, and at least one partially reflecting surface (22) located in the substrate (20) which is non-parallel to the major surfaces of the substrate wherein the source emits light waves located in a given field-of-view, that the light waves are collimated, that an angular resolution is defined for the optical device, and wherein the angular deviation between any two different rays located in one of the collimated light waves, is smaller than the angular resolution.

A programmable electronic closure system has a lock for operation by a key when an identification code of the key and a corresponding code of the lock match. The closure system can be programmed to modify the code data in both the key and the lock using an input device.
