Title: Self-adapting millimeter-wave network
Inventor: YINGAL LEIBA
IPC: H04W36/30
Filed: 2017-09-18
Abstract: System and methods to adapt a network of millimeter-wave communication nodes to a changing condition. The system detects a changing condition and concludes that the network needs to be adjusted. As a result, the system transitions, substantially instantaneously, between a current network topology to a new network topology, by instructing each of several millimeter- wave communication nodes to electronically steer the respective millimeter-wave beam away from current destination node and toward another destination node. The end result is that several of the beams change direction during a short period of time, thereby transitioning to the new network topology without impacting ongoing communication. In some embodiments, the transition between network topologies is done multiple times in a systematic fashion so as to generally find an optimal network topology and not as a response to a changing condition. In some embodiments, the transition between network topologies is a normal ongoing mode of operation.

Title: MOPA laser system with back reflection protection
Inventor: Nicoletta Haarlammert
IPC: H01S3/10
Filed: 2017-12-15
Abstract: The invention relates to a MOPA laser system having at least one laser oscillator (MO) which generates laser radiation at an emission wavelength (λ0), and having an optical amplifier (PA) after the laser oscillator (MO) in the direction of propagation of the laser radiation, which amplifier amplifies the laser radiation and thereby expands it spectrally to a useful bandwidth (∆λ). The problem addressed by the invention is that of providing an improved MOPA laser system which is designed for a high power of the amplified laser radiation and which is insensitive to back reflections. Unavoidable back reflections should neither influence the output power of the optical amplifier (PA) nor lead to the destruction of the laser oscillator (MO) or other components of the system. The invention solves this problem by arranging an optical band pass filter (BPF) between the laser oscillator (MO) and the amplifier (PA), which filter is transparent for laser radiation at the emission wavelength (λ0), wherein those spectral fractions of the reflecting laser radiation, i.e. the laser radiation incident on the band pass filter (BPF) contrary to the propagation direction, which lie outside the permitted range (4) in respect of wavelength, are reflected in the propagation direction at the band pass filter (BPF).

Inventor: THOMAS JOHN AUSTIN
IPC: A41D13/00
Filed: 2020-09-21
Abstract: A garment formed of a front fabric panel 17 and at least one further panel 19, 21, 23, said panels being joined along their lateral edges such that they define a waist opening 9, the front panel and further panel(s) being formed of elastically stretchable fabrics. The front panel defines 10-60% of the total length of the waist and is folded to define a front waist hem, the further panel(s) are folded to form a further waist hem, and the hems have a depth of at least 15mm. The garment is characterised in that the front panel extends at least 10% more under the same load than the further panel(s) in the waist direction. This results in the front panel exerting less force on the wearer’s abdomen. The further panel(s) might have their ability to expand restricted by way of a thermoplastic (37, figure 3) deposited within the hem, further preferably also comprising gripping elements (39, figure 3) on the inner surface. The further hem might have a greater depth than the front hem. The garment might be boxer shorts, leggings, cycling or swim shorts, and is particularly suited to sport or exercise.

Title: Vision Assessment
Inventor: HAZEL KAY
IPC: A61B3/028
Filed: 2020-12-08
Abstract: A method of assessing the vision of a user 4 alters the distance between the user and a symbol or optotype 2 being viewed whilst the size of the symbol may be kept constant. The visual acuity of the user can be defined in terms of the minimum visual angle at which the user is able to identify the optotype. To provide results for self-administration at home, a computing device such as a smart phone and/or laptop may display a symbol when positioned at different distances from a wall 3, receive an input from the user interpreting the symbol at each distance then provide a feedback assessment of vision based on the results. Where space is limited, the distance may be kept constant whilst the size of the optotype is decreased.

Title: Use of hydroxide ions as a heat source
Inventor: GELEIN DE KOEIJER
IPC: B01D53/34
Filed: 2021-06-09
Abstract: The use of hydroxide ions as a heat source in a carbon dioxide (CO2) absorption process. The hydroxide ions are preferably in aqueous solution together with one or more cations, such as those selected from the group consisting of potassium (K+), sodium (Na+) and lithium (Li+) and the concentration of hydroxide ions may be up to 30 mol%. The hydroxide ions may be generated via a process using energy which has not produced CO2 emissions, such as renewable energy. The CO2 absorption process may employ an aqueous hydroxide solution as a sorbent and process can occur at a temperature below 100 °C. Hydroxide ions generated in a desorption process may be recycled back to the absorption process. Advantageously the use of hydroxide ions could produce up to 50% more heat, relative to a process where hydroxide ions are absent.

Title: Actuators
Inventor: ANDREW BENJAMIN SIMPSON BROWN
IPC: G03B3/12
Filed: 2021-07-30
Abstract: An eight wire SMA actuator has a static part 3, a moving part 2 and eight shape memory alloy (SMA) wires 4 connected between them to drive the moving part 2 relative to the static part 3 with at least two degrees of freedom. Two of the SMA wires 4 are located on each of four sides s1-s4. On contraction, a first group 4(1,3,5,7) of four of the SMA wires each provide a force on the second part with a component in a first direction along the primary axis z, and a second group 4(2,4,6,8) of the other four of the SMA wires each provide a force on the second part 2 with a component in a second, opposite direction along the primary axis z. Each of the eight SMA wires 4 is foreshortened in the plane perpendicular to the principal axis relative to a length l of the side s, allowing a higher angle within the same overall height, which increases the resonant frequency and controllability of the actuator.
